8. Attach the 3/8” fuel line to the Straight Twist-Lok fitting first,
then connect to the fuel rail fitting on the EFI system.
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 secondary steel
fuel filter, cut fuel line to length as needed and secure with
a hose clamp.
10. Attach 5/16” fuel hose (not supplied) to the fuel sump vent
fitting and secure with a hose clamp.

Fuel Sump Vent
NOTE: The supplied 3/8” fuel hose is Twist-Lok and is NOT
recommended for use on the fuel sump vent fitting.
11. The fuel sump vent line MUST be routed 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.
WARNING: 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.
12. Reconnect the NEGATIVE (-) terminal on the battery. Verify
that the Fuel Sump power connector 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.
13. Once the Fuel Sump has been filled, connect the supplied
Fuel Sump pigtail to the Fuel Sump power connector
(see figure 1). NOTE: The supplied Fuel Sump pigtail is
designed to connect to Edelbrock EFI systems. If using
a different brand EFI system, cut and splice the pigtail
to an appropriate fuel pump power supply.
14. 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.
NOTE: The Fuel Sump will make a pumping/priming noise
for 5-8 seconds when the key is first turned on (when using
Edelbrock EFI systems). If Fuel Sump is not priming, verify
that the Fuel Sump harness is installed correctly.
15. If the Fuel Sump is priming, the Fuel Sump installation is
complete.
Fuel Pressure Regulator Adjustment: The fuel sump is factory
set to 58 psi. Adjust the fuel pressure by loosening the jam
nut on the regulator with a 9/16” wrench. Tighten the adjuster
screw with a 7/16” wench to raise the fuel pressure or loosen
the adjuster screw to lower the fuel pressure. When the desired
pressure is met, tighten the jam nut (snug) while holding the
adjuster screw in place. (See figure #5 for reference)
IMPORTANT: The Edelbrock Fuel Sump can be used with any
fuel injection system. The hose port on the pressure regulator
adjuster provides connection to engine vacuum for vacuum
compensating the fuel pressure. Different connections need to
be made to the vacuum nipple on the regulator depending upon
the location of the fuel injectors in the EFI system. If the fuel
injectors are located under the throttle blades or in the manifold
ports like Pro Flo 3, you need to connect a vacuum hose to a
ported fitting on the throttle body. If the injectors are above the
throttle blades, leave the port open to atmosphere.
WARNING!
The fuel sump vent line is a critical part of the Fuel Sump installation. These instructions MUST be followed for safe
and proper system operation. A fuel rated hose must be routed from the vent port (see figure #4) back to the fuel
tank. The fuel tank must also be vented if not originally equipped with a vent line or vented cap. If the vehicle has
a vent line, you can tee into this line. If no existing vent line to the fuel tank exists, you must plumb a new line to a
point above the maximum fuel level of the tank (at the top) or in the fill neck. DO NOT run a vent line from the Fuel
Sump to OPEN AIR in the engine compartment or pointed to the ground. DO NOT run the vent line into any part of the
air intake system. Proper routing of the vent line is not an option. This procedure is mandatory for your safety.
Edelbrock is not responsible for any fires, personal injuries, property damage or any other issues pertaining to
improper vent line routing and or failure to follow these instructions.
