1. Lift or appropriate jack

2. OSHA-approved jackstands

3. OSHA-approved fuel transfer pump

4. OSHA-approved fuel storage containers

5. Wire stripping and crimping tool

6. Various hand tools

• 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.

INSTALLATION PROCEDURE

• 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 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. 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.

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. 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).
