INSTALLATION INSTRUCTIONS
PLEASE study these instructions carefully before beginning this installation. This installation can be accomplished with common tools and
procedures. However, a familiarity with working on automotive fuel systems is highly recommended. If you do not feel comfortable performing
this installation or have never worked with automotive fuel systems before, it is highly recommended to have the installation completed by a
Professional Mechanic.
result in poor performance and engine or vehicle damage.
Monday - Friday, 7:00 am - 5:00 pm, Pacific Standard Time.
Make sure to perform the installation in a well ventilated area away from any potential fire hazards. Gasoline fumes
are toxic and are highly flammable.
This universal fuel sump system will provide the necessary high fuel pressure required for most EFI applications in vehicles originally designed
with carbureted fuel systems. For ease of installation, the factory carbureted fuel system will be used in conjunction with the universal fuel sump
system. This works by feeding the fuel sump, at standard Carb pressure (7 PSI max), using the factory fuel tank and mechanical fuel pump or
low pressure electric fuel pump. The sump will house a high pressure fuel pump, regulator and internal bypass. This will allow the desired fuel
pressure (#3605/36052 - 58 PSI, #3607 - 49 PSI) necessary to adequately operate EFI systems; all without the need for a fuel return line.
CAUTION: Due to the high fuel pressure used by the E-Street EFI system, the supplied 3/8 inch high pressure rubber fuel line MUST be
used as the primary fuel line. If supplying your own high pressure fuel line, a minimum of SAE J30R9 (100PSI) working pressure must be
used. Additional fuel fittings will be required.
Proper installation is the responsibility of the installer. Improper installation will void the manufacturer’s warranty and may
If you have any questions, please call our Technical Hotline at: 1-800-416-8628,
WARNING!
Prior to starting the installation, make sure to eliminate all potential fire hazards
as fuel leakage can occur when loosening the fuel system connections.

FUEL SUmP INSTALLATION
This is a general guideline for installing the Edelbrock Fuel
Sump System #3605 and #3607. If using #36052, additional
hardware mentioned in these instructions (i.e. fuel lines, fuel
filters, mounting brackets, harnesses and fittings) will have
to be supplied.
Make sure to perform the installation in a well ventilated area
away from any potential fire hazards. Gasoline fumes are toxic
and highly flammable.
NOTE: Depending on your application and specific routing
needs, additional fuel fittings may be required. These fittings
are available at your local Russell Performance dealer.
1. With the ignition off and the engine cool, disconnect the
NEGATIVE (-) terminal on the battery.
2. Release the fuel pressure in the fuel system by removing
the gas cap.
3. Determine the ideal mounting location for the Fuel Sump
using the supplied mounting hardware and brackets. The
universal mounting brackets included in this kit can be
mounted horizontally or vertically as shown below (see fig.
2).
NOTE: In addition to the universal bracket provided in this
kit, additional mounting brackets may be required to securely
mount the Fuel Sump. A template of the mounting holes is
provided on the last page of this installation instruction.
5. Assemble the Fuel Sump input line using one 90° Twist-Lok
fitting and the 3/8” fuel line. Install the 90° Twist-Lok fitting
onto the “IN” fitting on top of the Fuel Sump and route the
fuel line towards the 3/8” barb on the mechanical fuel pump.
Cut fuel line to length as needed and secure the fuel input
line to the mechanical fuel pump with a hose clamp.
NOTE: The Twist-Lok fittings do not require additional hose
clamps.
DO NOT route the fuel lines around sharp objects, moving
components or exhaust manifolds/headers.
6. Determine the ideal mounting location for the supplied steel
fuel filter and secure using the provided mounting clamp.
NOTE: The steel fuel filter must be used to avoid
contaminating the EFI System. Any failures associated with
contaminates will void the warranty of the Fuel Sump and
EFI System (if applicable).
7. Assemble the Fuel Sump output line using one 90° TwistLok fitting and the 3/8” fuel line. Install the 90° Twist-Lok
fitting onto the “OUT” fitting on top of the Fuel Sump and
route the fuel line towards the fuel filter. Cut fuel line to
length as needed and secure the fuel output line to fuel filter
with a hose clamp.
8. Attach the 3/8” fuel line to the Straight Twist-Lok fitting and
connect to the fuel rail fitting on the EFI system.
Fig. 2
4. Remove the fuel output line (mechanical pump to carburetor)
from the factory mechanical fuel pump and carburetor (if
applicable).
NOTE: The mechanical fuel pump needs to be configured
with a 3/8” barb fitting that will route to the inlet fitting on
the fuel sump. Brass compression nuts and tube adaptors
are provided for your convenience. Depending on your
mechanical fuel pump configuration, additional fittings may
be required.
NOTE: Additional fittings may be required depending on
the EFI application used. These are available at your local
Russell Performance dealer.
9. Route the fuel line from the EFI fuel rail to the fuel filter, cut
fuel line to length as needed and secure with a hose clamp.
10. Attach a 3/8” fuel hose (not supplied) to the 90° quick
connect fitting and secure with a hose clamp.
NOTE: The supplied 3/8” fuel hose is Twist-Lok and is not
recommended for use on the quick connect fitting.
11. Connect the 90° quick connect fitting to the Vent Tube barb
on top of the Fuel Sump. The vent line must be routed to a
charcoal canister, fuel tank vent (if equipped), or back to the
fuel tank (fuel tank must have a vent or use a vented cap).
NOTE: If charcoal canister has been removed, the existing
hard line from the canister to the tank is convenient for use
as a vent line.
If using a low pressure (7 PSI MAX) electric fuel pump, the
fuel output will route and connect to the inlet fitting on the
fuel sump.

12. If using the Edelbrock E-Street EFI system, a Fuel Pump
Relay Harness #36054 (supplied in #3606 kits only) must
be used. Damage to the ECU will occur if the Fuel Pump
Relay Harness is not used. The Fuel Pump Relay Harness
connects to the Fuel Pump connector on the E-Street main
harness. The power lead on the relay harness connects to a
Constant +12v source (see figure 3). DO NOT connect the
relay harness to the Fuel Sump at this time.
NOTE: A Fuel Pump Relay harness is required to properly
operate the Fuel Sump. If using on other EFI systems, the
relay harness will connect to the fuel pump leads on the EFI
harness. Modifications to the relay harness connector may
be required.

NOTE: The following steps must be performed to properly
fill the Fuel Sump prior to starting the vehicle. Failure to do
so will damage the fuel pump inside the sump and void your
warranty.
14. Once the Fuel Sump has been filled, connect the supplied
Fuel Sump pigtail to the Fuel Sump power connector (see
figure 1). Then connect the Fuel Sump pigtail to the Fuel
Pump Relay harness. Modifications to the relay harness
may be required (see figure 3).
NOTE: If using E-Street system #3606, the Fuel Sump
Harness included, can connect directly to the Fuel Sump and
Fuel Pump Relay harness.
15. Turn the key to the “ON” position but DO NOT start the
vehicle. With the key in the “ON” position, check all fuel
connections for leaks. If leaks are present, immediately turn
the key off and repair all leaks before continuing.
16. If leaks are not present, turn the key off and back to the
“ON” position to verify the Fuel Sump is priming.
NOTE: Fuel Sump will make a pumping/priming noise for
5-8 seconds when the key is first turned on (when using the
Edelbrock E-Street EFI system). If Fuel Sump is not priming,
verify that the Fuel Sump harness is installed correctly.
17. If the Fuel Sump is priming, the Fuel Sump installation is
complete.
NOTE: It is not advised to start the vehicle until the
installation of the EFI system is complete. Please refer to
the EFI System’s Installation Manual for details.
13. Reconnect the NEGATIVE (-) terminal on the battery. Verify
that the Fuel Pump Relay Harness IS NOT connected to the
fuel sump. Turn the key to the “ON” position and crank the
engine for 10 seconds. Turn the key to the “OFF” position
and wait for 30 seconds. Repeat this procedure one more
time to properly fill the fuel sump.
NOTE: The engine will not start. If it does, it will stall as
there is no fuel going into the engine. This is normal.
