Can't fill gas tank, pleading for help.
 

1999 F250 V10 4x4 Ex. Cab and 8ft. bed.

It takes about 5-6 minutes per gallon, if that. And that's only at stations that can pump that slow. So, basicly, the truck isn't getting driven.

Cleaned the canister. Wouldn't fill. Disconected the charcoal canister, won't fill.

When I bought the truck, there wasn't a bed on it, so I have nothing to reference to know how the filler neck and vent hose are suppposed to be orientated.

Could some post or link to how those lines are supposed to be routed? I pretty much made it up as I went along.

the hose may be pinched somewhere too, if i was you i woud get underneath the truck and check all your lines and your hose that goes from your gas tank to where the gas nozzle goes in. i had the same prob with my old truck and thats what i had done when i replaced the bed in it.

5-6 mins/gallon is extremely slow, assuming you are not exagerating. I don't think that will be from a vent problem. It could be the fill hose is kinked. It could also be something has become lodged in the fill tube, like the bottle cap from the top of a Techron bottle, for example. See if you can get a siphon hose to go all the way down the throat.

The plastic tube part that penetrates the tank, and connects to the fill hose, is only about 1" diameter.

Definitely a pinch or blockage in the main fill pipe. I had the same problem with my Mustang after I replaced the fuel pump. I set the filler wrong and it twisted.

I have replaced the fill hose with a new hose.

I haven't replaced the vent hose, but I've temporarily spliced in some plastic pieces where it looked linked.

Is the filler neck supposed to point straight down?

Could be someone attempted to steal gas and bent the valve just inside the filler neck? This happened to my uncles jeep.

*looked kinked

I don't think so, because I can get in around 1/5th of gallon before it cuts off the first time. Like Im filling up the filler neck and the gas can't get in the tank. That's what makes ne think it's a venting issue. Like I can't displace the air in the tank.

I guess Ill just have to pull the bed back off.

The vent hose is about the only thing I haven't replaced. I don't think I can get to it with the bed on.

There are some TSB for this problem I think. Check the TSB's


I found this under 2009 F250's. It may still be relevent to you. I don't know. But anyway here it is...

I have heard of the problem v10zilla mentioned prior to the 09 models. Definately good idea to check carbon filter.

I had been having the same problems with my 2002 Excursion 7.3L, in that I could not
get fuel into it. I have been struggling for months standing at the pump
for 20 minutes at a time trying to put 5 gallons into the tank..
I read every forum on Fuel neck problems I could find.
I even duct taped a garden hose to my shopvac hose in hopes that it was just
a dirty screen, and that maybe by sticking the garden hose down the neck
that the suction would clear the debris
or dislodge or latch onto whatever it was that was stuck in there....
I even thought that maybe a Tree Hugger had maliciously dropped
a golf ball down my fill neck just to teach me a lesson..
While it was a good idea. The shopvac didnt work...
So last night I decided to tear into it....
Taking the fuel neck off was fairly straight forward. 3 Screws and two hose clamps..
I checked the neck very closely and ramed wire through it several times
hoping to knock out any blockage.. There was no blockages.
So I went back under the excursion and took the main fill hose off of the tank.
It was tight but I accomplished it with a 1/4 inch ratchet. Once I had
the main rubber fill tube off. I scootched up inside as far as I possibly could and put a flashlight
on the main fill nipple.. Lo and behold, there was a round piece of cardboard from
the top of one of my Diesel Additives stuck in there... Not sure how or when it happend
but I am thankful it wasnt an expensive fix..
I am sure, that I am not the only one that this has happened too. I put alot of
additives in it over the winter months too keep my fuel from gelling,
and all it took was one screw up.
The repair took me all of about 45 minutes, alot of grunting and wishing I had
a 3rd elbow on my arm.
Getting the metal fill neck off of the rubber fill and vent tubes was the hardest part.
Before I put it back together I sprayed the outside of the neck and inside
of the fill tube and vent tube with lubricant and it popped in easy as pie.
To help keep from doing this again I will be buying single use bottles from now on..
The top came from one of those big bottles that treats 3 or 4 tank fulls.. So apparently
I didntn notice on the 2nd or 3rd time I used it that the cardboard was stuck on top
of the bottle when I pulled the cap off.
I hope this helps someone solve their problems..
In retrospect.. using my air compressor I probly could have put air onto
the little vent at the left side of the fill neck and blown that piece of cardboard out of the
neck.. That would have been awesome! oh well, its fixed now.
Good luck to you all..

1/5th of a gallon is about all your fill neck will hold.. You have
a blockage.. read my other post. I think it will help you..

Nice story, kip-66. Glad it worked out to be something so simple. And I hope the OP has an equally easy fix.

Well, fixed it.

Removed the bed again. No blockages.

Turns out I didn't have the filler neck in the correct orientation. Fills up just fine now.

The last time I put the bed on it really sucked with just two people, trying to lift it over the tires. This time I got creative with a small tractor and ratchet straps.
