COMP PUMP SERIES 110FI IN-LINE

ELECTRIC FUEL PUMP PART NO. 11106M

INSTALLATION INSTRUCTIONS

FORM INST11106M (Rev A) 05/10

Parts included in this kit:
1 - Comp Pump 100FI Series electric in-line fuel pump
2 - Mounting brackets

Please read these instructions completely before
installing your new fuel pump. Installation of this pump
requires detailed knowledge of repair and modifications
to a high performance fuel system. We recommend that
a qualified automotive technician perform the installation
procedure.

NOTE: DO NOT RUN THIS PUMP WITHOUT FUEL (EXCEPT FOR
A BRIEF PERIOD WHILE PRIMING)

CAUTION: Please make sure to wear appropriate safety apparel.
Work in a well ventilated area. Extinguish any open flames
and eliminate any source of ignition or sparks in the area.

WARNING: The fuel system operates under pressure. Do not
open the fuel system until the pressure has been relieved.
Please refer to your appropriate service manual for the correct
procedure to relieve the fuel system pressure. Fuel leakage
will occur when loosening any fuel system connections. Be
sure to be ready to safely contain any fuel leakage.

PERFORMANCE SPECIFICATIONS

Outlet Pressure/Flow:

110 gph free flow with 12.5 volts
85 gph @ 45 PSI with 12.5 volts
60 gph @ 65 PSI with 12.5 volts

Maximum recommended operating pressure: 65 PSI
continuous, 90 PSI intermittent

Mallory part no. 11106M fuel pump is rated for both
gasoline and gasoline/ethanol blends up to E85.

Mallory part no. 11106M fuel pump utilizes port style
O-ring fittings; -8 AN inlet and -6 AN outlet. Mallory part
no. 30606 and 30808 fittings or their equivalents are
recommended. DO NOT use pipe thread of thread sealant
with these fittings.

A high capacity fuel pre-filter with a 40 micron to no
greater than 100 micro rated element must be installed in
the fuel line between the tank and the fuel pump inlet.
Mallory part no. 3175 or equivalent is recommended.

PERFORMANCE SPECIFICATIONS

A by-pass or return style fuel pressure regulator MUST
be used with this fuel pump. We recommend the Mallory
part no. 4305M for systems running from 30 to 90 PSI.

Gravity feed this pump by mounting it as low and as
close as possible to the fuel tank. The installation of either
a rear mount reservoir style sump or a high flow capacity
fuel tank pickup in your stock tank is highly recommended.
These will insure that the fuel pump is able to self prime
and avoid pump starvation and cavitation. Failure to follow
these recommendations will result in poor fuel system
performance and drastically shorten the fuel pumps life.

Improper fuel pump installation will void all product warranties.

INSTALLATION

1. Wait for the engine to cool. Make sure the ignition system
is off or disconnect the negative battery cable. Relieve
the fuel system pressure.

2. Raise and secure the vehicle to allow working access
under the vehicle. Following the appropriate service
manual procedure to; disconnect the existing fuel
pump lines, plug all open fuel lines to keep fuel from
draining and debris from entering, remove the existing
fuel pump.

3. Install either the after-market fuel tank rear mount
sump or high flow capacity fuel tank pickup per the
manufactures instructions.

4. Assemble the mounting brackets onto the fuel pump.
Determine the new fuel pump mounting location.
Remember it needs to be as low and as close to the
fuel tanks as possible.

5. Make sure that the fuel pump location will accommodate
the mounting brackets. Also make sure that the fuel
pump, lines and pre-filter locations will be free from
any interference with the exhaust system as well as
clear of any moving suspension system or drive train
components. Keep the fuel pump clear of any road
obstacles or debris that can be kicked up by the tires.
Make sure you have access to the pre-filter so that the
element can be periodically cleaned and/or changed.

6. Use the mount brackets as a template, mark and drill
the four mounting holes.

7. Install the fuel pump making sure the fuel pump is facing
the correct direction. The outlet side is the same side
as the fuel pump’s electrical connections.

8. Install the inlet and outlet fittings. Connect the fuel
tank pickup line to the pre-filter and the fuel pre-filter
to the fuel pump inlet. The pre-filter can be directly
mounted to the fuel pump inlet or via a short section of
fuel line if necessary. Make sure that if you must use
angled fittings, that they are of a sweep design to
minimize any flow restrictions. Most fuel system problems
are due to flow restrictions on the inlet side of the fuel
pump. If at all possible do NOT use forged hard
angled fittings.

9. Make sure you are using a correctly rated high pressure
fuel line from the fuel pump forward. Make sure that
you are using a high flow 10 micro fuel filter between
the fuel pump and the fuel pressure regulator. We
recommend the Mallory part no. 3160 fuel filter or
equivalent. Make sure you are using a return style fuel
pressure regulator.

10. Fuel pump wiring – We recommend that you use a 30

amp universal electric fuel pump relay and harness
installation kit. Please fellow the wiring kit’s installation
instructions. If you are not using a relay harnesses kit,
connect a 12ga BLACK wire to the negative (-) terminal
on the fuel pump and to a quality ground location
such as an engine ground or the negative battery
terminal to chassis ground location. Connect a RED
12ga wire from a 12v key-on switched connection,
such as a 30 amp relay to the positive (+) terminal on
the fuel pump. Use a 30amp inline fuse. Double check
to make sure the power to the pump is only on when
the ignition key is on.

11. Check for leaks – Turn the ignition key to the “Run”
position without starting the engine. This will power
up the fuel pump. Check for any fuel leaks at all the
connections. Fix and repair any leaks immediately
before operating the vehicle.

If you have any questions or problems, please contact our
Technical Service department at 216.688.8300 8:00am- 5:00pm
Monday- Friday EST.

When installing the pump, do not over tighten the nuts
on the electrical posts. These need to be a

snug fit

only

. Over tightening these connections can result in
damaging internal connections and create a no run
condition. This is considered damage at installation
and not warrantied.
