Fuel Pump Removal & Installation To Remove:
WARNING
The fuel system is under constant pressure, even when the engine is off. This pressure must be released before servicing the fuel pump module.
  1. Drain fuel tank and remove the tank.
  2. Thoroughly wash and clean area around pump module to prevent contaminants from entering tank.
  3. The plastic fuel pump module locknut is threaded onto fuel tank. Install special tool #6856 to fuel pump module locknut and remove locknut. The fuel pump module will spring up when locknut is removed.
  4. Remove the module from fuel tank.
To Install:
CAUTION
Whenever the fuel pump module is serviced, the module gasket must be replaced.
  1. Thoroughly clean locknut threads and mating fuel tank threads. Use a solution of soap and water. Do not use carburetor cleaner to clean threads.
  2. Using new gasket, position fuel pump module into opening in fuel tank.
  3. Apply clean water to locknut threads.
  4. Position locknut over top of fuel pump module.
  5. Rotate module until arrow is pointed toward front of vehicle (12 o'clock position). This step must be done to prevent float/float rod assembly from contacting sides of fuel tank.
  6. Install special tool #6856 to the locknut.
  7. Tighten the locknut to 55 ft-lb (74 Nm).
  8. Rotate fuel filter/fuel pressure regulator until its fitting is pointed to 10 o'clock position.
  9. Install the fuel tank.

Electric Fuel Pump - REMOVAL & INSTALLATION
(see Figures 1, 2 and 3)

Fig. 1: Remove the nuts retaining the access cover in the trunk

Fig. 2: Once the cover is removed, access to the pump is obtained

Fig. 3: Note the alignment marks must be met to install the pump correctly

An electric fuel pump is used with fuel injection systems in order to provide higher and more uniform fuel pressures. It is located in the tank. To perform the testing or servicing, you will need a DRB III or equivalent scan tool.
  1. Release the fuel system pressure.
  2. Disconnect the negative battery cable.
  3. Open the trunk lid, then remove the trunk liner.
  4. Remove the access panel fasteners.
  5. Remove the access panel and gasket. Inspect the gasket for damage. If necessary, replace the gasket.
  6. Disconnect the electrical wiring from the top of the pump module.
  7. Disconnect the fuel supply and return tubes from the fuel pump module.
  8. Disconnect the hose from the pressure relief/rollover valve.
  9. A band clamp fastens the pump module to the tank. The module rises up from the tank after loosening the clamp.
  10. Loosen the band clamp until the pump module rises up from the tank.

WARNING The pump reservoir may contain fuel. Do not spill fuel while removing the module.
  1. To absorb any possible spillage, place a shop towel around the access opening. Without removing the modular, tip it backwards to allow fuel in the reservoir to run down the side and back into the tank.
  2. The float arm of the sensor catches on the inside of the tank while removing the module. Tilt the module to the one side when removing it from the tank.
  3. Remove the pump module and gasket from the tank.
  4. Drain the remainder of fuel from the reservoir before servicing the pump module.

To install:
The fuel pump module and tank have alignment marks. The tank has two molded lines at the ten o'clock position. The fuel pump has a triangular alignment mark. Align the marks to correctly position the pump.
  1. With a new gasket, insert the pump straight into the tank to set the float on the bottom. Align the marks on the pump and tank.
  2. Seat the pump to tank by pushing the top downward. Make sure the gasket does not slip over the outside or inside edge of the tank lip. While holding the pump in the seated position, place the band clamp over the lip of the tank and edge of the pump. Tighten the band clamp to 31 inch lbs. (4 Nm). Do not over tighten.
  3. Install the fuel tubes over the return and supply nipples on the module.
  4. Connect the vent line to the pressure relief/rollover valve.
  5. Attach the electrical wiring to the pump.
  6. Using a DRB III or equivalent scan tool, pressurize the fuel system.
  7. Check for leaks.
  8. Install the access cover and gasket. Tighten the fasteners.
  9. Install the trunk liner.
  10. Connect the negative battery cable.

Hope this help to solve your problem (remember rated and comment this).

I need to replace the fuel pump in my 1985 Chevy S10 pickup, need all help. What is the procedures?


EXACT PROCEDURE ! Please Rate Me Fairly for this!! Thank you And Good Luck !!


ELECTRIC PUMP

REMOVAL
  1. Before servicing the fuel pump the fuel system pressure must be relieved. See: Fuel Pressure Release
  2. Disconnect the negative battery cable.
  3. Raise the car on a hoist.
  4. Remove the fuel tank. See Fuel Tank / Service and Repair.
  5. Remove the fuel tank sending unit and pump assembly by turning the cam lock ring counterclockwise. Lift assembly from the fuel tank.
  6. Pull the fuel pump up into the attaching hose while pulling outward away from the bottom support. Take care to prevent damage to the rubber insulator and strainer during removal. After the pump assembly is clear of the bottom support, pull the pump assembly out of the rubber connector for removal. NOTE: Inspect the fuel pump attaching hose for any signs of deterioration. Also check the rubber sound insulator at the bottom of the pump. Replace damaged or deteriorated parts.
INSTALLATION
  1. Push the fuel pump assembly into the attaching hose.
  2. Position the fuel tank sending unit and pump assembly into the fuel tank. Use a new "O" ring seal. NOTE: Care should be taken not to fold over or twist the strainer when installing the sending unit as this will restrict the flow of fuel. Also, verify that the strainer does not block the full travel of the float arm.
  3. Install cam lock over the assembly and lock by turning clockwise.
  4. Reinstall fuel tank.
MECHANICAL PUMP

REMOVAL and INSTALLATION

NOTE: To ease pump installation, rotate the camshaft so the camshaft eccentric is out of the way of the fuel pump rocker arm.

  1. Disconnect fuel lines from fuel pump.
  2. Remove fuel pump mounting bolts and the fuel pump.
  3. Remove all gasket material from the pump and block gasket surfaces. Apply sealer to both sides of new gasket.
  4. Position gasket on pump flange and hold pump in position against its mounting surface. Make sure rocker arm is riding on camshaft eccentric.
  5. Press pump tight against its mounting. Install retaining screws and tighten them alternately.
  6. Connect fuel lines. Then operate engine and check for leaks.
