Introduction
The Mityvac Fuel Injection Cleaner can perform
two types of engine cleaning services:
1. Fuel Injector Cleaning
2. Air Induction System Cleaning
Fuel Injector Cleaning is performed by installing
the Cleaner directly into the fuel delivery system,
where it dispenses a specially formulated solution
directly into the engine. The solution dissolves
deposits from the injectors and prevents future
buildup.
Air Induction System Cleaning is performed by
inserting a nozzle (sold separately) into the air
intake stream. The Cleaner delivers cleaning
solution to the nozzle under pressure, where it
is injected into the air stream as a fine mist. The
solution coats the inside of the throttle body,
intake manifold, and valves, to loosen and
dissolve carbon deposits. The deposits are then
burned off by engine combustion.
Both types of cleaning services can enhance
engine performance, improve fuel economy,
reduce maintenance and improve emissions.

Application Precautions
This equipment is intended for use by vehicle
service professionals with experience and knowledge of its application and limitations. While it is
designed for servicing a variety of vehicles in a
safe and convenient manner, due to variations
between vehicle manufacturers, makes, models
and years, use of this equipment is not always
feasible, possible, or recommended.
Use common sense when operating this equipment. If something does not seem or feel right,
stop immediately and consult a professional with
knowledge of the application. Don’t force the use
of this equipment on an application for which it is
not intended.
The procedures documented in this manual
are to serve as guidelines for general use of
this equipment. In addition to these guidelines,
always follow the vehicle manufacturer’s recommended procedures when attempting to use this
equipment.
When installing this equipment for induction
system cleaning, insure the cleaning solution is
introduced downstream from the mass airflow
sensor. Installing the nozzle upstream of the sensor can cause permanent damage to the sensor.
Harsh cleaning solutions can damage some
delicate idle air control valves. If unsure of the
effect of the cleaning solution on the IAC for the
vehicle, consult the vehicle’s manufacturer for
further information.
When performing a fuel injector cleaning service,
keep the Cleaner pressure below the rated fuel
pressure of the vehicle to prevent damage to the
injectors, and to prevent cleaning solution from
bypassing the regulator and entering the fuel
tank.

Proper Use, Care and Servicing
With proper care and maintenance, the Fuel Injection Cleaner
will provide years of reliable service.
The Fuel Injection Cleaner is designed for cleaning modern
fuel delivery systems on vehicles equipped with gasoline
powered combustion engines.
• After use, always empty and drain any remaining cleaning
solution from the Cleaner before storage.
• Always store the Cleaner in an upright position, in an
open environment and away from extreme heat and open
flames. We recommend hanging it with the wall mount
bracket included with the kit.
• Inspect components regularly for damage, and replace or
repair as necessary:
- Check hoses for cracks and cuts
- Check adapters for damage and wear to threads and
sealing surfaces
- Check female quick-connects for wear and cuts
to o-rings
• After installing the Cleaner and pressurizing the system,
check the Cleaner Assembly for leaks. If any leaks are
evident, immediately relieve the pressure, disconnect the
Cleaner, and send it to an authorized service center for
repair.
• The Cleaner has a sintered bronze filter element at the
end of the fluid pickup tube that extends into the canister.
This filter may be removed and cleaned with a solvent.
Ensure the filter is rid of all solvent before replacing.
Cleaning Solutions
The use of the Mityvac Fuel Injection Cleaner requires the
separate purchase of cleaning solution(s) specially formulated
for fuel injector or induction system cleaning using a canister
style cleaner. We recommend use of the following solutions:
OTC Part #7000A INJECT-R KLEEN
OTC Part #7904 D-KARBONIZER
BG Part #211 ISC Induction System Cleaner
BG Part #206 Air Intake System Cleaner
BG Part #210 Fuel Injection System Cleaner
Check the specifications for the cleaning solution prior to
use. Ensure it is specified for use with canister-style cleaning
systems, and is formulated for the type of cleaning service to
be performed.
WARNING
Fuel tank additives are not formulated for use in the
Mityvac Fuel Injection Cleaner.
Page Number - 8 Form 801817
Connections
The outlet port of the fuel injection cleaner utilizes a special
male quick-connect fitting (Fig. 1). This fitting was selected
for several important reasons;
1. It conforms to the SAE J2044 specification for fuel fittings
2. It is a common fuel delivery system connection on which
many manufacturers are standardizing
3. It does not restrict fuel flow
4. The female quick-connect on the mating connection
hose, releases with a simple push-button action. No
special tools are required to disconnect the fittings.
The mating connection hose as well as the adapters and
fittings that connect the Cleaner into the fuel delivery system
utilize the same SAE J2044 endform (Fig. 2).
To secure the male to female connection, simply push the
male endform into the female quick-connect until it snaps
securely into place (Fig. 3). Always test the connection by
trying to pull it apart without pressing the release button.
Figure 1
Adapters
Mityvac offers a selection of adapters for connecting the
Cleaner to the fuel injection systems of a wide range of
automotive makes and models. The chart on pages 6 and 7
outlines the adapters available, and their applications. Each
adapter is etched with an identification number for easy
reference. Most of these adapters come standard with
the Mityvac FST. If you do not own an FST, they must be
purchased separately from an authorized Mityvac distributor.
Adapters can be purchased separately in sets according to
the order number indicated in the chart.
In most cases, selecting and installing adapters to the fuel injection system and connecting the Cleaner, is straightforward
and logical. Simply match the fuel system connection to the
equivalent adapter, and install it as outlined in the instructions
later in this manual.

Set-up and Operation
Fuel Injector Cleaning
When performing fuel injector cleaning, the Cleaner should
be installed as close as possible to the inlet of the fuel rail.
On most vehicle models the fuel supply line can be disconnect directly from the end of the fuel rail, and the Cleaner
connected in its place. If not, the Cleaner can often be
connected just before the fuel rail at an alternate connection
such as a flexible rubber to steel hose connection or at the
outlet of the fuel filter.
1. Run the car until the engine is at operating temperature.
2. Place the vehicle transmission in park or neutral, apply
the parking brake, and turn off the key.
3. Unscrew the Fuel Injection Cleaner canister bottle from
the manifold assembly and pour in the appropriate fuel
injector cleaning solution.
4. Screw the canister back into the manifold assembly,
and hang the Cleaner under the vehicle’s hood using the
chain provided.

5. Close the Cleaner inlet and outlet valves.
6. Close the relief valve by turning it clockwise until tight.
7. Pull out on the regulator adjustment knob to unlock it,
and adjust the regulator to fully open by rotating the knob
counter-clockwise.
8. Connect the cleaner supply hose to the outlet of the
Cleaner (Fig. 4).
9. Connect shop air supply to the Cleaner inlet. Ensure the
shop air pressure is no greater than 150 psi (10 bar)
(Fig. 5).
10. Follow the vehicle manufacturer’s recommended proce-
dure to relieve the pressure from the vehicle fuel delivery
system.
11. If not done in the previous step, disable the fuel pump
by removing the fuse or relay, or unplugging it from the
power supply.
12. Locate the fuel supply line to the engine’s fuel rail, and
select the best location to disconnect the supply line and
install the hose extending from the Cleaner.
13. Remove or disconnect any obstacles required to gain
access to the connection, and place shop towels under
and around the connection to adsorb fuel from the
disconnected line.
Note: To minimize fuel spillage and reduce the amount
of time the fuel line is disconnected, try to identify the
type of connection before disconnecting the fuel line, and
have the required connection adapter readily available.
Page Number - 10 Form 801817
14. Follow the vehicle manufacturer’s service information for
the proper method to disconnect the fuel line. Special
wrenches or disconnect tools may be required (Fig. 6).
Prop the loose end of the fuel supply line in a position to
prevent fuel from leaking out.
WARNING
Avoid spilling fuel on hot engine parts. Clean up any fuel
spills immediately after they occur.
15. Install the appropriate adapter to the fuel line running to
the fuel rail, or directly onto the fuel rail.
Note: If the fuel line connection used by the vehicle
manufacturer is a 3/8” quick-connect style (SAE J2044),
an adapter is not required (Fig. 7).
16. Connect the hose extending from the Cleaner to the
other end of the adapter.
17. Open the inlet valve located between the shop air
connection and the regulator (Fig. 8).
18. Slowly close the air regulator by turning the knob clock-
wise until the pressure gauge reads 5 psi (.3 bar) below
normal operating fuel pressure (Fig. 9).
The value for normal operating fuel pressure can be
located in a service guide or repair manual for the
specific vehicle.
19. Lock the regulator adjustment by pushing in on the knob.
Figure 6
Figure 7
20. Open the outlet valve between the canister and the hose
connection (Fig. 10).
21. Before proceeding:
a. Double check the connections. The Cleaner should
be installed such that the shop air enters the Cleaner,
and cleaning solution flows from the Cleaner into the
fuel rail.
b. Ensure the canister bottle is screwed securely into the
manifold, and is not cross-threaded.
c. Route the Cleaner and shop air hoses, and the
loose end of the fuel supply line away from rotating
engine components, belts, fans, and hot exhaust
components.
d. Remove the fuel spillage rags.
e. Reconnect components such as PCV tubes,
wiring harnesses, vacuum tubes, etc., that were
disconnected to gain access to the fuel line
connection.

22. Start the engine and allow it to idle using the cleaning
solution inside the canister.
23. Run the engine until all the cleaning solution in the
canister has been used. This should take around
10 to 15 minutes.
Use wide-open-throttle blips two or three times during
this procedure to exercise the injectors and help clear
them of deposits.
24. Once the cleaning solution has been used and the car
stalls, close the air inlet valve (Fig. 11).
25. Open the relief valve to release the system pressure
(Fig. 12).
26. Wrap a rag around the connection between the cleaner
hose and the vehicle’s fuel system, and disconnect the
hose.

Intake System Decarbonizing
(requires MVA550 Decarb Nozzle, sold separately)
The Decarb Nozzle (MVA550) should be installed inside the
air intake duct, where it clamps to the inlet of the throttle
body. It must be installed downstream of the mass airflow
sensor (Fig. 13), so the cleaning solution does not come in
contact with the delicate sensor. In some cases, the mass
airflow sensor is mounted in the throttle body. Do not use the
Cleaner to perform air induction cleaning on this type of air
intake system.
The spray nozzle should point directly at the center of the
throttle plate without touching it. With the nozzle inserted into
the air stream, the small S-shaped steel tube should pass
between the air duct and the throttle body at the point where
the duct clamps onto the throttle body inlet. The supply hose
connection end of the nozzle assembly should extend outside
of the duct and the whole assembly held in place with the
worm clamp that secures the air duct to the throttle body. The
S-shaped steel tube can be bent into any shape required for
the installation.
1. Run the car until the engine is at operating temperature.

3. Loosen the clamp securing the air intake duct to the inlet
of the throttle body (Fig. 14).
4. Slide the air intake duct off the throttle body and the
install the Decarb Nozzle so the spray nozzle end is
aimed at the center of the throttle plate, but not
touching it (Fig. 15).
5. With the nozzle pointed at the throttle plate, bend and
position the S-shaped steel tube so the air intake duct
can be slipped over it (Fig. 16).
6. Secure the adapter in place by tightening the hose
clamp. For additional support and to ensure the
Decarb Nozzle remains in the proper position, an
extended clamp, part no. MVA551 is available for
separate purchase. See page 3 for additional details.
7. Unscrew the Cleaner canister bottle from the manifold
assembly and pour in the appropriate decarbonizing
solution.
8. Screw the canister back into the manifold assembly,
and hang the Cleaner under the vehicle’s hood using the
chain provided.

12. Connect one end of the Cleaner Hose to the outlet of
the Cleaner (Fig. 17), the other end to inlet of the Decarb
Adapter (Fig. 18).
13. Connect shop air supply to the Cleaner inlet. Ensure the
shop air pressure is no greater than 150 psi (10 bar)
(Fig. 19).
14. Start the vehicle and allow it to idle.
15. Return to the Cleaner and open the air inlet valve
(Fig. 20).
16. Rotate the regulator adjustment knob clockwise until the
pressure gauge reads approximately 60 psi (4 bar)
(Fig. 21).
17. Open the outlet valve to allow the cleaning solution to
spray into the air stream (Fig. 22).
At 60 psi (4 bar) pressure, it will take approximately
8 minutes to inject 12 oz (350 ml) of cleaning solution
into the air stream.
Figure 18
18. Close the air inlet valve when the canister is empty of
solution.
19. Turn off the car.
20. Allow the pressure to return to zero, and disconnect and
disassemble the Cleaner. Properly dispose of any unused
cleaning solution.
21. Remove the nozzle from the air induction system and
re-secure the air intake hose.
Note: Do not start the engine for 30 minutes. This will
allow the solution to soften and dissolve the carbon
deposits. After 30 minutes, test drive the vehicle for at
least 15 minutes to flush carbon deposits out of the
system.
