SOURCE: Replacing fuel filler neck on 2000 Crown Vic

Good news, no the tank doesn't have to come down. However, there needs to be less than 3/4 tank. Jack it up and set on a jack stand, remove the wheel, four screws housing to pipe, filler pipe sensing hose from filler pipe, screw retaining the cap, four retaining screws from filler pipe, screw from filler pipe retainer, slide into the tank until it can be rotated and pulled out through the fender. lube the tank grommet with clean oil and reverse the removal for install.

Did you check the vent tube alongside the filler neck? If it is pinched or blocked with something, just what you describe will happen. The air in the tank needs some way to escape to make room for the gas, and it should be through the vent tube. If it's bent, pinched, blocked, you will have a hard time pumping gas in.

SOURCE: very hard to fill my

Not sure but maybe the fuel pump is very hot making the fuel boil. Maybe check to see if the tank is hot, ( touch it ) if it is the fuel pump or the fuel filter needs to be changed. The pump is very powerful and with the filter clogged up it'll work real hard to deliver the fuel at the correct pressure. This will make the fuel ump real hot hick may make it boil the cool fuel added. Does it do this if the tank has more fuel in it? A fuel pump that's getting this hot isn't a good thing and should be followed up on. The other thing that might be happening is the fuel inlet hose is picnced and the fuel is being reversed. But it seems like the lavel won't matter. Maybe the tank is'nt venting corectly and the tank is being sucked flat as it emplties and as it fills it goes back in shape. ( alot less likly.)

My 2000 ford taurus won't fuel up and we have checked the evap and the vents and they are good the checked the power coming from the slosh module and there wasn't any could that be why it isn't fueling

This is from Fred's Auto on a Ford Taurus Forum:
Hello to your question on the ford taurus being hard to put gas in . replace the filler neck. or remove the filler neck. and when you get the neck out of the tank you will see another tube/hose in the center of the filler tube cut about 2" of the end of the center tube. the problem is that the tube over time with pressure in the tank and tube being soaked in the gas for along period time it gets soft and tube starts to close shut. i find that if you put a hard piece pipe on the end you will never have this problem again. also there is a vent tube on top of the tank(witch you do not have to remove the tank) and make sure it is not crushed shut.. this is a very easy repair. this will 100% fix your problem.

Randy said: well here is what I found. There was a small piece of hose inside my fuel fill hose. It just seem like something was blocking the fuel, so I went under and tried to squeeze on the hose and I couldnot squeeze it into like you should be able to do. so I took the hose clamp loose and hose off end of fill neck and reached inside with needle nose pliers and pulled out a smaller section of hose that I am being now told should not have been in there,by service managers.
Another guy suggests starting your car with the gas cap off.
And some others said look inside for a tiny piece of foil that accidentally came off the top of a fuel additive.
I hope that helps!

How to replace fuel tank filler tube?

Brother John, you've removed as much as you can for access to the filler. Remove the hose clamps/bands that secure the fill tube and vent tube and then remove the screws around the gas cap that secure the fill tube to the body. With the gas cap off, go below and pull the hose and filler neck down and work the hoses lose with a pair of channel lock pliers and sticking a screwdriver between the metal tube and hose to break the seal. Put on the new filler neck and stick it back up in the body and put the screws back in. THEN put the hose clamps back up and tighten them, put the gas cap back on and your done.

The hose is on the side of the gas cap and it runs down to the bottom of the quarter panel. When I filled the gas tank up, gas comes out of this hose. We just had the fuel pump replaced. Its not leaking...

There are normally two hose lines from the fuel filler that run to the tank. The larger one carries the fuel from the nozzle to the tank. The smaller one is a vent hose that allows vapors to leave the top of the tank while filling. These vapors come back to the nozzle area and can be vented and/or collected by the nozzle depending upon air pollution standards in your area. If your second hose is running to the bottom of the quarter panel, it is probably the vent hose that may not have been reconnected at the top of the tank when the fuel pump was replaced. The fuel running down there is from kickback fuel at the time the pump shuts off. The real problem is that the vent line is open on top of the tank and when the tank is full, that can allow vapors and fuel to escape out of there and it could contact hot exhaust areas - a major fire or explosion hazard. Have this inspected and repaired IMMEDIATELY.

Fuling problem, gas backs up in filler and cuts off, hard to fill with fuling cutting off every 3-5 seconds.

That would be your carbon canister. You will need to replace that to fix your problem. It will be somewhere between your fill opening and the gas tank. Look for a line running from filler tube that would be it. Also you may have an access hole for your fuel pump in trunk, if you do, you can probably see the top of it in the direction of your filler tube. Hope you find it. Shouldn't be to bad, but that is your problem.

Can't fuel xg350 2002 at gas station difficult

there is a tube that runs along side the filler neck to the gas tank, this tube allows air to escape from the gas tank as you fill it, if it gets kinked or obstructed then you have a hard fill situation, pull the filler neck/vent assembly out and replace it.
