Im searching for the location of my fuel filter


searching why, (buy an FSM and no more guessing...? )
basic service?
low fuel pressure? why?

ive got near a 1/2 million + miles on jeeps since 1988.
never stranded, but i do my service,.
my last chick-o-dee. was 99. with 5sp, all with that.
my 08 JK same.
the fuel filters on old loop systems is in the front of the tank
then later, , EPA forced most parts into tank with the new loop
or dead head systems. (EPA wants fuel cold .so, that is it)
i dont find parts hard to find, jeeps excel at that. vast resources.
nor hard electrical if you had a 2007+ then that be different.

so

ill paste the FSM page on this topic

he 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. Relieve the fuel system pressure. Refer to Section 5 for the proper procedure.
  3. Remove the fuel tank assembly.
  4. Clean the area around the fuel filter/regulator.
  5. Disengage the retaining clamp from the top of the filter/regulator assembly. Discard the retaining clamp.
  6. 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.
  7. Remove and discard the mounting gasket below the filter/regulator.
  8. 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.
  9. Clean the recessed area in the pump module where the filter/regulator assembly is to be installed.
  10. Check the replacement filter/regulator assembly to make sure that the new O-rings are already installed on the assembly.
  11. Apply a small amount of clean engine oil to the O-rings.
  12. Install a new gasket on top of the fuel pump module.
  13. 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).
  14. The arrow on top of the fuel pump module should be pointed towards the front of the vehicle (12 O'clock position).
  15. Turn the filter/regulator assembly until the supply tube (fitting) is pointed to the 11 O'clock position.
  16. Install new retainer clamp (the clamp snaps over the top of the filter/regulator and locks to the flanges on the pump module).
  17. Install the fuel tank assembly.
  18. Connect the negative battery cable.
  19. end

how is that ?

Electric Fuel Pump - REMOVAL & INSTALLATION

CAUTION Fuel injection systems remain under pressure, even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.
  1. If equipped with air suspension, the air suspension switch, located on the right-hand side of the luggage compartment, must be turned to the OFF position before raising the vehicle.
  2. Disconnect the negative battery cable.
  3. Relieve fuel system pressure using the recommended procedure.
  4. Raise and safely support the vehicle.
  5. Remove the fuel tank from the vehicle and place on a suitable work bench.
  6. Remove any dirt that has accumulated around the fuel pump retaining flange so it will not enter the tank during pump removal and installation.
  7. On 1989-94 models, turn the fuel pump locking ring counterclockwise and remove the locking ring.
  8. On 1995-98 models, remove 6 retaining bolts around the perimeter of the fuel pump module.
  9. Remove the fuel pump/sending unit assembly. Remove and discard the seal ring.
To install:
  1. Clean the fuel pump mounting flange, fuel tank mounting surface and seal ring groove.
  2. Apply a light coating of grease on a new seal ring to hold it in place during assembly and install in the seal ring groove.
  3. Install the fuel pump/sending unit assembly carefully to ensure the filter is not damaged. Make sure the locating keys are in the keyways and the seal ring remains in the groove.
  4. Hold the pump assembly in place and install the locking ring finger-tight. Make sure all the locking tabs are under the tank lock ring tabs.
  5. Rotate the locking ring clockwise until the ring is against the stops.
  6. Install the fuel tank into the vehicle.
  7. Lower the vehicle.
  8. If equipped with air suspension, turn the air suspension switch to the ON position.
  9. Add a minimum of 10 gallons of fuel to the tank and check for leaks.
  10. Reconnect the negative battery cable.
  11. Turn the ignition switch to the RUN position several times to pressurize the fuel system. Check for fuel leaks and correct as necessary.
  12. Start the engine and check for leaks.
  13. Road test the vehicle and check for proper operation.

Fuel pump 98 s10


Hi:
You must first drain and lower the fuel tank, as your pump is mounted inside. With the fuel tank supported, undo the tank mounting straps, and the filler hose, then slowly lower it until you can disconnect the fuel lines and electrical harness. The pump assembly is now accessable. Remove and replace the assembly , then reinstall the tank .
