http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

i have the KJ pages here. (line # messed up)
Two different procedures may be used to drain fuel
tank: through the fuel fill fitting on tank, or using a
scan tool.
The quickest draining procedure involves removing
the rubber fuel fill hose (7) (Fig. 25) from fuel tank
fitting.
As an alternative procedure, the electric fuel pump
may be activated allowing tank to be drained at fuel
rail connection. Refer to DRB scan tool for fuel pump
activation procedures. Before disconnecting fuel line
at fuel rail, release fuel pressure. Refer to the Fuel
System Pressure Release Procedure for procedures.
Attach end of special test hose tool number 6541,
6539, 6631 or 6923 at fuel rail disconnection (tool
number will depend on model and/or engine application).
Position opposite end of this hose tool to an
approved gasoline draining station. Activate fuel
pump and drain tank until empty.
If electric fuel pump is not operating, fuel must be
drained through fuel fill fitting at tank. Refer to following
procedures.
(1) Release fuel system pressure.
(2) Raise vehicle.
(3) If equipped, remove fuel tank skid plate.
(4) Thoroughly clean area around fuel fill fitting
(6) (Fig. 26) and rubber fuel fill hose (1) at side of
fuel tank. After cleaning, loosen fuel fill hose clamp
(2) at tank.
(5) Before removing rubber hose (1) (Fig. 26) from
fitting, note hose orientation while referring to marks
(3) and (4).
6) Disconnect rubber fuel fill hose at fuel tank fitting
(2) (Fig. 27). Using an approved gas holding
tank, drain fuel tank through this fitting.
Tank Removal
(1) If equipped, remove fuel tank skid plate and
tow hooks. Certain equipment packages will also
require removal of the trailer hitch. Refer to Tow
Hooks, Trailer Hitch or Skid Plate in 23, Body for
removal/installation procedures.
(2) Disconnect and separate fresh air tube (6) (Fig.
28) quick-connect fitting.
(3) Disconnect air tubes at front of NVLD pump
(9) (Fig. 28).
(4) Disconnect NVLD pump (9) (Fig. 28) electrical
connector.
(5) Disconnect fuel pump module electrical connector
jumper. This is located near front of fuel tank.
(6) Support tank with a hydraulic jack.
(7) Remove 4 fuel tank strap bolts (10) (Fig. 28) (2
at front of tank; 2 at rear of tank), and remove both
tank support straps.
(8) Carefully lower tank a few inches.
(9) Continue lowering tank while guiding remaining
hoses and lines through plastic isolator sleeve (3)
(Fig. 29).
(10) If fuel tank is to be replaced, remove NVLD
pump and fuel pump module from tank. Refer to
Fuel Pump Module Removal/Installation procedures.

I would check the fuel lines where they attach to the sending unit. The rubber inside of the nylon weave is probably rotten and sucking air instead of pulling the fuel up and out of the tank.

How to replace a fuel pump on a1997 Chev Venture



  1. Properly relieve the fuel system pressure and install a pressure test gauge according to the tool manufacturers instructions.
  2. Turn the ignition switch to the ON position for 3 seconds, then turn to the OFF position for 5 seconds. Repeat this procedure two or three times to pressurize the system. Again turn the switch to the ON position.
    1. On TBI equipped vehicles, the gauge should read a static pressure of between 9 and 13 psi (62-89kPa)
    2. On SFI equipped vehicles, the gauge should read a static pressure of between 41 and 47 psi (248-325kPa)
    3. If not, check for a clogged fuel filter, a kinked fuel line, or an inoperative fuel pump.
  3. On TBI equipped vehicles, the fuel pressure will drop after the fuel pump stops running due to a controlled bleed in the fuel system. Use of the fuel pressure gauge will determine if the fuel system pressure is enough for the engine to start and run.
  4. No fuel spray from the injector indicates a faulty fuel or ignition system or no PCM control of the injector.
  5. This test will determine if the ignition control module is not generating the reference pulse or if the wiring or PCM are at fault. By touching and removing a test light to B+ on CKT 430 (purple/white wire from the ignition system), a reference pulse should be generated. If the injector test light blinks, the PCM and wiring are OK.







If the pump tests bad...
Disconnect the negative battery cable.
  1. Relieve the fuel system pressure.
  2. Block the front wheels and raise and support the rear of the vehicle safely. Make sure the rear is high enough to accommodate the removal of the fuel cell.
  3. Loosen the fuel filler neck connecting tube clamp at the tank.
  4. Wrap a shop towel around the fuel filter neck connecting tube and slowly remove the fuel filler neck connecting tube from the fuel tank.
  5. Position a siphon hose into the fuel tank through the fuel filler opening. Place the other end into an approved container with enough capacity to hold the fuel in the tank. Siphon the fuel.

Fuel filter location


The fuel filter is attached to the frame in front of the gas tank, under the driver side of the car. It is an approx 3-4 cylinder attached at either end by a pressurized fuel lines.

If you are about to change it you must relieve the pressure in the fuel line before you start, and it is also recommended that you disconnect the neg. battery cable.

Location of fuel filter,its boggs down when applying gas to speed up,was told fuel filter is clogged but i cant find it


Open the gas door and remove the gas cap. This will help to alleviate the pressure in the fuel line.
  • Step 2 Crawl under the Bravado and trace the fuel line from the fuel tank. The filter is an in-line filter and attached to the fuel line.
  • Step 3 Unsnap the fuel inlet line from the filter. The filter is equipped with a quick-connect fitting that can be unsnapped and pulled off the piping of the filter.
  • Step 4 Remove the outlet line off the piping of the filter. This line can removed the same as the inlet line.
  • Step 5 Unbolt the mounting bracket holding the filter in place with a socket wrench. The bracket is held in place by one bolt.
    Replacing the Fuel Filter
  • Step 1 Attach the new fuel filter to the mounting bracket and secure it to the frame. Tighten the bracket snugly with the socket wrench. Ensure the arrow on the filter is facing toward the front of the vehicle. The arrow indicates fuel flow direction.
  • Step 2 Snap the inlet line on the filter. Push the line on to the piping of the filter till it clicks in place.
  • Step 3 Connect the outlet line on the filter. This line will snap in place as well.
  • Step 4 Screw the gas cap back on to the fuel door. Close the gas door.
  • Step 5 Crank up the SUV and let it idle. Ensure there is no hesitation or stalling

    How to change fuel pump 1990 cadillac seville


    The fuel pump and sending unit is located in the tank. I hope your tank is empty, if not you will need to siphon it out. It is dangerous with the gasoline, and remember the fumes burn, not gas. You start by removing the filler hose, then loosen straps, detach sending unit wire and fuel line, then lower tank. Then unscrew the sending unit/pump and replace. reinstall.

    72 Pontiac GTO, been sitting for 8 years. I can't


    You hit the nail on the head. Chances are the sending unit filter "sock" is clogged. Most of the time you can clear it by blowing compressed air back through the tank.
    I would however, inspect the suction line from the fuel pump to the tank for rust obstruction and hoses for de-lamination.
    Disconnect the line just before it goes into the tank and try to blow air through it just to make sure it is not rusted shut.
    Good luck, let me know.

    Locating the fuel filter


    You didn't state the year or engine size,,,, On the firewall,( passenger side, back of engine compartment, it's round) on fuel injected models, relieve pressure of fuel line before beginning- gas cap off,also must release pressure on fuel injected models- some have pressure release on top of filter, others on fuel rail,this will be a bolt on top of a bolt. Hold the bottom bolt (w/ open end wrench, loosen top bolt w/ 6mm wrench. Cover with rag, so you don't have gas shooting up in your face. Carb models: have 2 filters, one inline in engine compartment, 2nd under car attached to fuel tank. Open gas cap to relieve pressure before starting removal on carb models. countrycurt0
