INSTALLATION NOTES
• Remember: When working on your vehicle, especially when oil or fuel is present, always work in a well ventilated area. Keep all sparks, open flames, or other sources of ignition away from the work area. Failure
to do so could result in a fire or explosion causing vehicle or property damage, personal injury, and/or death.
• Before Beginning: This installation can be accomplished using common tools and procedures. However, you should have
a basic knowledge of automotive repair and modification and be familiar with and comfortable with working on your vehicle.
If you do not feel comfortable working on your vehicle, it is recommended to have the installation completed by a
professional mechanic. Using a factory service manual for your vehicle for reference is helpful.
• Note: Steps shown in these instructions are intended as a general guideline only. If you are not an experienced mechanic,
you should have a copy of your service manual on hand. The installation procedure for replacing your factory fuel pump is
covered in full detail in your factory service manual.

INSTALLATION PROCEDURE
(Note: This rotary fuel injection pump will not work
on carbureted fuel systems. It is for electronic fuel
injection only.)
(Note: The word “bracket” used throughout these
instructions refers to the fuel pump mounting
bracket and fuel level sender assembly.)
PREPARATION
1. Make sure the engine is cool and the vehicle is on level
ground. Set the parking brake.
2. Remove the negative (ground) cable from the battery
and position it so that it cannot make a connection to
the battery during the fuel pump installation
procedure.
3. Relieve fuel system pressure by using a pressure
gauge tool, Ford Service tool # T80L-9974-B or
equivalent. Connect the pressure gauge to the
Schrader valve located on the engine fuel rail. Slowly
open the pressure gauge valve and drain the fuel into
a suitable container to relieve the fuel system
pressure. (This procedure is necessary since the fuel
system can retain gasoline under pressure for a
considerable period of time. Opening a pressurized
line could spray fuel, creating a risk of fire or personal
injury.)
4. Drain the fuel tank. Use an OSHA-approved gasoline
transfer pump, and remove as much fuel as possible
through the fuel tank filler neck. Store the fuel in
approved safety containers only.
5. Lift and safely support the vehicle with approved
safety stands with enough height to gain clearance to
remove the fuel tank. If lifting only the rear of the
vehicle, remember to block the front wheels.
6. Once the vehicle is lifted and supported, an alternate
method of fuel removal may be implemented.
Determine which line is the fuel return line going back
to the fuel tank (See Fig. 1). Trace the return line
back from the injectors and remove it from the
bracket. Securely attach a hose to the exposed fuel
return tube leading into the tank, and draw the
remaining fuel out and into an approved container.
(Note: Regardless of the method used to remove
fuel from the tank, it is important to remove as much
fuel as possible before removing the tank. This is
required to help prevent fuel spillage, and injury
from excessive weight while removing the tank).

FUEL TANK REMOVAL
(Caution: The fuel tank can be quite awkward to
remove due to its size and weight. Obtain help during
its removal).
(Note: The following instructions may not be specific
to your particular vehicle. See your factory service
manual for specific instructions).
1. Prior to removing the retaining clips in the fuel line
connectors, note their styles and respective fuel line
location. The 1/4” fuel line connector uses a duckbill
style retainer, and the 5/16” fuel line connector uses a
hairpin style clip. The specific service manual for this
vehicle has a section on fuel lines, fuel line connectors,
and fuel line connector retainers that may be referred to,
if necessary, for help in removing the clips and/or fuel
lines. Remove the retaining clips from the fuel line
connectors and remove the fuel lines from the pump
bracket. Check for and remove any other hoses that may
be attached to the fuel tank.
2. Disconnect the electrical connector at the fuel tank to
main harness connector. Support and partially lower the
tank, if needed.
3. Remove the fuel filler neck, if necessary.
4. Support the fuel tank and remove the retaining straps to
allow the tank to be removed from the vehicle. Remove
the fuel tank being careful not to spill any remaining fuel.
5. Note the condition and position of all fuel tank mounting
pads and insulators used to isolate the fuel tank from the
vehicle body. Mislocated, deteriorated, or incorrect pads
and/or insulators can cause objectionable transmission of
fuel pump noise into the vehicle.

BRACKET REMOVAL
1. Thoroughly clean all dirt and debris from the top of the
tank. Clean out any dirt from around the locking ring
and retainer. This must be done to prevent dirt of
foreign material from falling into the fuel tank while
removing the bracket.
2. Lubricate the locking ring with penetrating oil to assist
in its removal. Remove the locking ring by rotating in a
counterclockwise direction.
This can best be
accomplished safely by using the proper service tool as
specified in the factory service manual. Using the
proper tool is ideal. However, the locking ring can be
removed by other methods. Whichever method you
use, do not use any method that could potentially cause
sparks resulting in fire or explosion.
3. Once the locking ring is removed, carefully remove the
bracket from the fuel tank. Be careful not to bend the
float arm or scratch the float when it is removed.
Discard the old fuel tank to bracket o-ring seal.

1. Note the position of the fuel pickup filter in relation to the
bracket before removing the filter. Remove and discard
the filter.
2. Prior to removing the lead wires, inspect the terminal
ends attached to the fuel pump. Some vehicles use a
locking terminal on which a tab must be depressed to
release the terminal. Remove the wires from the fuel
pump without damaging the terminal ends, as they are to
be reused. Note which wire is positive (+), and which
wire is negative (-).
3. Remove the four screws that hold the upper and lower
bracket sections together. Remove the lower section and
fuel pump isolator and set them aside.
4. Note the fuel pump’s orientation. Remove the hose
clamps and remove the fuel pump and fuel hose from the
pump bracket.
5. Install the new fuel hose onto the new fuel pump outlet
fitting and place the hose clamps over the fuel hose.
Install the fuel hose onto the pump bracket. With the fuel
pump properly positioned, tighten the hose clamps.
6. Install the fuel pump isolator over the end of the fuel
pump inlet. Place the lower section of the pump bracket
over the pump inlet and install the screws. Make sure
that the fuel pump is properly positioned in the
assembled bracket. If not, reposition the fuel pump as
necessary.
7. Install the lead wires onto the pump terminals, making
sure that proper polarity is maintained.
8. While maintaining proper orientation, push the new filter
onto the pump inlet until it is fully seated.
9. Thoroughly inspect the pump and bracket for any
possible defects before installation into the tank.
BRACKET INSTALLATION
1. Inspect the fuel tank for dirt and debris. If the amount of
dirt or debris is excessive, clean the fuel tank before
installing the bracket assembly.
2. Inspect the bracket to make sure it is clean and ready for
installation.
3. Place the supplied fuel tank o-ring seal in the groove at
the fuel tank opening. Place the bracket assembly into
the tank using care not to disturb the o-ring seal. Also
use care not to fold or twist the filter, as this could cause
restricted fuel flow. Install the locking ring and rotate it
clockwise until it is properly seated against the stops.
Check service manual for an approved sealant for locking
ring.

FUEL TANK INSTALLATION
1. Inspect the condition and location of all tank mounting
pads, insulators and brackets. Defective, missing or
mislocated pads and insulators will cause the
transmission of excessive noise into the vehicle.
2. Install the new fuel line retaining clips, 1/4” duckbill
style and 5/16” hair pin style, into their respectively
sized fuel line connector. With the 1/4” duckbill
retainer properly installed, the serrated edges should
protrude through the side opening of the fuel line
connector. The 5/16” hairpin clip is installed with the
triangular portion of the clip facing away from the fuel
line connector opening. (See Fig. 3)
