Replace fuel pump assembly or pump - 2001 Lincoln Navigator

Some Impalas have the module assembly and the fuel filter is made into that assembly and is not serviceable without changing the whole assembly inside the gas tank which could be expensive.

Replacing fuel pressure regulator on Toyota Vitz, Yaris and Eco:
1. Remove rear seat.
2. Remove rear service hole cover.
3. Remove fuel pump and vapor pressure connector.
4. Start the engine till it stops on it own and switch the ignition to OFF.
5. Remove the tube joint clip, wrap a piece of cloth around it and pull out the main tube.
6. Pinch the fuel emission tube connector clip and pull it out.
7. Remove the 8 bolts and fuel tank vent tube set plate.
8. Remove the fuel pump assembly.
9. Remove the O ring from fuel pump assembly.
10. With help of screw driver remove the fuel pump locking plate.
11. Remove the fuel pump regulator with screw driver a bit force fully.
12. Assemble the fuel pump assembly in the reverse sequence of dis assembly.



Hope that it works. Thank you for visiting Fixya.

Are you looking to find just a fuel pump? Or are you needing to replace the COMPLETE module assembly? Both are available at most any parts supply store. In MOST cases, all that needs to be replaced is just the fuel pump itself. However, the module assembly has to be replaced due to severe rust and corrosion on many of the Chevrolet trucks. See the pictures below. The first picture is of a fuel pump kit. The second picture is of a complete fuel pump assembly with the hanger assembly and fuel level sensor included.

IF YOU HAVE FUEL FILTER WITH FUEL PUMP ASSEMBLY YOU HAVE TO REPLACE FUEL PUMP ASSEMBLY REMOVE THE REAR SEAT BENCH IN ORDER TO REPLACE THE FUEL PUMP ASSEMBLY. NOW IF YOU HAVE FUEL PRESSURE REGULATOR AND FUEL FILTER AS ONE UNIT.BECAUSE FUEL PRESSURE REGULATOR BUILT TO THE FUEL FILTER.TO REPLACE FUEL FILTER, FIRST DEPRESSURIZE THE FUEL SYSTEM BY REMOVING THE FUEL PUMP RELAY LOCATED ON THE COWL.THEN CRANK ENGINE UNTIL IT DIES LACK OF FUEL.THE CRANK ENGINE OVER FEW TIMES TO MAKE SURE ALL FUEL OUT THE FUEL LINES.LOCATION OF FUEL FILTER UNDER THE VECHICLE MOUNTED TO THE LEFT SIDE OF THE CHASIS.

The fuel filter is an integral component of the fuel pressure regulator, which is mounted on top of the fuel pump module, located in the fuel tank. When the fuel filter/regulator assembly requires service, the fuel tank must be removed from the vehicle, however, the fuel pump module does not need to be removed.

1. Disconnect the battery ground cable.
2. You dont have to relieve your fuel systems pressure because your jeep has an automatic bleeder.
   
3. Remove the fuel tank assembly.
4. Clean the area around the fuel filter/regulator.

Fig. Fig. 5: Remove the fuel filter/pressure regulator retaining clip from the top of the assembly

Fig. Fig. 6: Replace the old fuel filter/pressure regulator mounting gasket

1. Disengage the retaining clamp from the top of the filter/regulator assembly. Discard the retaining clamp.
2. Using 2 small prying tools, pry the filter/regulator assembly out from the top of the fuel pump module. The filter/regulator assembly will unsnap from the fuel pump module.
3. Remove and discard the mounting gasket below the filter/regulator.
4. Before discarding the fuel filter/pressure regulator assembly, inspect the assembly to verify that the O-rings are intact. If the smallest of the 2 O-rings cannot be found on the bottom of the filter/regulator, it may be necessary to remove it from the fuel inlet passage in the fuel pump module.

To install:

Fig. Fig. 7: Check the condition of the fuel filter/pressure regulator O-rings

1. Clean the recessed area in the pump module where the filter/regulator assembly is to be installed.
2. Check the replacement filter/regulator assembly to make sure that the new O-rings are already installed on the assembly.
3. Apply a small amount of clean engine oil to the O-rings.
4. Install a new gasket on top of the fuel pump module.
5. Press the new fuel filter/pressure regulator assembly into the top of the fuel pump module until it snaps into position (a positive click must be heard or felt).
6. The arrow on top of the fuel pump module should be pointed towards the front of the vehicle (12 O&rsquoclock position).
7. Turn the filter/regulator assembly until the supply tube (fitting) is pointed to the 11 O&rsquoclock position.
8. Install new retainer clamp (the clamp snaps over the top of the filter/regulator and locks to the flanges on the pump module).
9. Install the fuel tank assembly.
10. Connect the negative battery cable.

Since this vehicle, (1994 Plymouth Voyager), is fuel injected, the fule pump assembly is located within the fuel tank. Replacement cost will vary, depending on your ability to lower the fuel tank and replace the part yourself. The fuel pump assembly ranges in price, from $95, to $140, depending on where you purchase it. The particular parts suppliers I use on a regular basis have listings for the fuel pump assembly, so finding a replacement part won't be hard at all. Though I haven't replaced a fuel pump in this exact vehicle, typically chrysler/plymouth/dodge, vehicles don't require any special tools to disconnect fuel lines, electrical connecters, and remove assembly from tank. Note: if you do this yourself, do NOT, cross-thread the pump locking ring, if it is a screw on type, as this WILL result in fuel leakage! If you have to have a repair facility do this work, I would estimate about 200 dollars in labor charges, (that's what I'd charge a customer in my shop) So, you should be looking at no more than $350, to $400 max with part and labor.

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.
