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.

id just crawl under car and gander, at fuel line but here we go
ill do it , online for you.
4Liter 98

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 ?

    Preparation
  1. Siphon as much fuel out of the tank as possible with a vacuum pump and deposit it into a gas can.
  2. Unplug the fuel pump inertia switch located behind the trim panel on the right side of the trunk. Start the engine and wait for it to stall.
  3. Disconnect the negative battery cable in the engine compartment. Loosen the clamp nut for the battery's black cable with a wrench and remove the cable from the battery terminal.
  4. Raise the car with its own floor jack and support it on jack stands, available from any auto parts store. Support the car on its rear end where the fuel cap and tank are located.
  5. Removing the Tank
  6. Open the gas cap door and remove the three bolts on the metal flange surrounding the filler neck (the pipe that you pump gasoline into) with a wrench.
  7. Disconnect any metal braces between the filler tube and the car body and supporting the tube. Remove their bolts or screws with a wrench/screwdriver.

  8. Disconnect the fuel and vapor line clamps with a screwdriver, then disconnect the fuel pump electrical connector and the connector to the emission shutoff valve.
  9. Raise a floor jack under the fuel tank under the right rear corner of the car near the fuel cap. Place a block of wood large enough to cover the entire top part of the jack to protect the tank.
  10. Unbolt the tank's support straps twrapped around the bottom of the tank with a wrench. Disconnect any other fuel lines and electrical connectors remaining on the top of the tank; press on their quick-connect fittings.
  11. Removing the Pump
  12. Tap the fuel pump assembly's locking ring counterclockwise with a wood rod or brass punch until it loosens.
  13. Lift the long, curved fuel pump module out of the tank until you can reach its locking tabs, then squeeze the tabs together with your fingers and remove the fuel pump module from the tank. Pull off and discard the lock ring gasket from the top of the module.
  14. Separate the fuel pump from the assembly by removing its clamp with pliers, disconnecting its electrical connector with pliers and removing its mounting screws. Use a Torx wrench to remove the screws.
  15. Clean the fuel pump's mounting flange, tank mounting surface and seal ring groove with acetone or lacquer thinner and a clean rag.
  16. Detach the strainer from the assembly by removing its C-clip with a small flat screwdriver. Wash the strainer with carburetor cleaner spray and reconnect it to the assembly. Clip the C-clip in place by hand.
  17. Installation
  18. Mount the replacement fuel pump in place on the module using its mounting screws and the Torx wrench, then plug in the electrical connector and connect the clamp by hand.
  19. Align the fuel pump assembly with the retainer within the tank and push it into the retainer with your hands until the tabs click into place.
  20. Install the pump assembly's sender plate by hand. Make sure the locating keys are in the keyways and the O-ring is in place.
  21. Install a new seal ring on the fuel pump module by pushing it in place on the locking ring's underside; rub heavy grease on the seal ring to hold it in place. Insert the module into the hole in the tank and turn the locking ring clockwise to lock it in place.
  22. Connect the fuel tank to the car in the reverse order of removal--raise it back into position with the floor jack, connect the fuel lines and electrical connectors strap it in place with the straps.
  23. Lower the car and reconnect the battery cable. Connect the fuel pump inertia switch and press its reset button to energize the pump

  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.

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 .
