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.
end , tank out.

Is difficult to fill gas tank


Gas pump nozzles have a device in the end that when gasoline runs back up into it, it turns off the fuel flow." There's a tiny hole near the bottom of the gas pump nozzle connected to a small tube.
Normally, air flows through that tube while you're filling and the gas keeps flowing as long as you hold down on the trigger. When that hole gets covered by gasoline (when your tank is full), a vacuum forms inside the nozzle and an automatic shutoff switch gets tripped, turning off the flow of gas with a thunk. Next time your fueling up try to reposition the nozzle.

2002 ford ranger gas issues


Okay I got tired of this and did something about it . so here is the solution . Pull off the bed . 6 bolts , hit them with a 2 pound sledge hammer and use a impact or a big 1/2 drive . Disconnect tail light harness on drivers side just above bumper area. undo screws on gas tank filler . two people can lift off bed . on top of the spare tire you will see the charcoal canister . About a foot long and black with a solenoid on the drivers side .connected to this solenoid by a cigar sized hose is a black box with another hose on the other side . This is a air filter . Lets in air when the solenoid opens so the fumes can travel back up the line . Notice that the open end hose is just right for collecting all the dirt and water that flies up there . This canister as it is marked has some foam inside like a lawn mower air filter . either go buy another at the dealer or simply tap it on the truck frame and get all the dirt out and blow out with air hose would be good if it is wet inside . Blow in it to make sure air flows freely through it . Put it back on .

Okay if that just happens to not be it here is how you find out what is it . After removing the bed make sure the vents on top of the gas tank are not plugged by blowing and sucking on them . Then unhook the fume line from the solenoid on the charcoal canister . Drive , I know no lights for breaks , to gas station and start filling up . If it splashes out then it is on the tank side . If not then plug up the line you removed and fill. If it splashes out then it is after the solenoid . Put thumb over other end of solenoid where the air filter is attached after removing the filter hose of course . If it splashes out then it is the air filter .
Make sure you point that hose on the end of the air filter at a downward angle so it does not collect water and dirt again . Stupid Ford makers .

Process of elimination.

I am so glad I can now fill my tank . Why in the he## can not all these mechanics on all these forums come up with the answer ? Or even the dealership.

The car seems to have an obstruction in the gas line, won't take gasoline easily from the punp. Turns pump off continuosly.


Dan the reason it takes it from a gas can is there is no pressure building up in the line as you would have from a gas tank. As you fill the tanks the air inside of the tank has to go out as the tank fills up. I would suggest checking the fill hose thats connected to the gas tanks and the spout inlet where you put the hose to fill the tanks and check for kinks in the hose. Second there should be a vent hose from the tanks that connects to the spout also check it for kinks or blockage this would prevent air from escaping from the tank causing the gas pump to cut off due to the rapid filling of the tank without the air being able to escape. Hope this helps

Service engine soon light came on, replaced gas cap it went off but a week later it came back on, when it try to fuel the truck it spill the gas back out like it is a full tank


One of the most common causes, is blockage in the venting system from fuel entering the vent lines and into the charcoal canister, the fuel gets absorbed by the charcoal canister causing it to swell and block vent lines. the gas tank contains both fuel and air. when you fill it up the gas displaces the air and the air has to go somewhere. but the air that is displaced is full of gas vapor so the gas vapor goes to the vent lines and into the charcoal canister, when the charcoal canister swells up it prevents the air from escaping the tank, canister could be clogged,canister filter may need replacement,electrical connection to the close valve may be open,canisterf might be damaged,purge valve from canister might be clogged,vent hoses might be clogged, the vent hose could be clogged, or the vent hose may have a kink. all this is caused by overfilling the gas tank, getting that last drop of gas in the neck of the fill tube.
good luck!

Gas tank over flows when filling up at the pump


This is the same issues I'm having. Is there any answer to this?

After putting gasoline in my car


Raise the car w/ a jack and place on safety stands after your next fill up. Look at gas tank, vent hoses, fill hose, fuel lines , something is definitely leaking. It could be anything from rusty deteriorating gas tank, or fuel lines, to a loose connection of the fill pipe, rotted, split vent line, etc. Check this out asap as this sounds like a serious safety concern, you don't want to be driving a fire bomb

When i try to pump gas in the tank even though it is not full gas will come back out as if it is to full


Spyder web in vent (that lets air out while u fill)
Try cleaning the lines going to the fill check valve or cleaning the lines going to it. It might be on or near the charcoal canistor or behing or on top the tank.
Or replace valve and lines
