• 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.
• Note: This rotary fuel injection pump will not work on
carbureted fuel systems. It is for electronic fuel injection
• Note: The word “bracket” used throughout these
instructions refers to the fuel pump mounting bracket
and fuel level sender assembly.
1. Make sure the engine is cool and the vehicle is on level
ground. Set the parking brake.
2. Relieve any pressure in the fuel tank by removing the
gas cap.
3. Relieve the fuel system pressure. (Note: If this
procedure is not followed, damage to the
injector(s) and/or other fuel system components
could occur.). Begin by locating and unplugging the
fuel injector wiring harness. Ground one terminal.
Apply battery voltage to the other terminal for five to
ten seconds to open the injector. This procedure is
necessary to prevent fuel from spraying when
disconnecting fuel lines. Spraying fuel could result in a
fire hazard.
4. 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.
5. Some vehicles require removal of the fuel tank to
access the fuel pump bracket. Some require removing
the rear seat, an access panel, and possibly the trunk
liner to access the pump bracket. In those vehicles that
require fuel tank removal, see the “Fuel Tank Removal”
section. On those that do not, remove the necessary
items and gain access to the top of the fuel tank and
the fuel pump bracket and continue on to the “Bracket
Removal” section.
(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. 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.
2. 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.
3. 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).

4. Disconnect the electrical connector at the fuel tank to
main harness connector. Disconnect the fuel lines
leading to the tank. Support and partially lower the
tank, if needed.
5. Remove the fuel filler neck, if necessary.
6. 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
7. 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.
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 or
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, and remove the locking ring using the
proper tool, as specified in the factory service
manual, or use another suitable method that CANNOT
potentially cause sparks resulting in fire or explosion.
Rotate the locking ring in a counter-clockwise direction
to remove it.
3. Carefully remove the bracket from the fuel tank. Use
care not to damage the float or float arm, if the float
assembly is part of the bracket (See Fig. 2).
• Note: See Fig. 2 and 3 for reference during the
removal and installation procedure.
1. Remove the filter. The filter may be attached with a
clamp. If so, cut and discard the clamp. If not, remove
the filter by grasping and pulling it away from the
assembly. Discard the filter.
2. Disconnect the electrical connections to the pump. Be
sure to note the polarity of the connections. (Note: On
some applications the connectors will be
soldered to the pump’s terminals. To remove, cut
the wires as close as possible to the terminals on
the pump).
3. Remove the hose clamps, cut the rubber hose, and
remove any pump mounting hardware.
4. Invert the bracket assembly, and pull down on the fuel
pump until the inlet end clears the pump support.
Swing it to the side, and remove the pump from the
bracket’s fuel outlet tube. Save the fuel pump rubber
grommet(s) for use in mounting the new pump. Also
remove the fuel pump isolator at this time. (Note: Some
applications will require a metal band to be cut, which
retains the pump.)
5. Remove the cut hose piece from the bracket tube and
discard along with the used hose clamps. Remove the
pump to filter adapter by pressing on the retaining tabs
and discard it.
