My truck vomits!..

[4x4xFORD]

I have this problem where I can only pump gas about a 1/3rd of the way on the gas nozzle, otherwise it will just puke it right back out of the filler pipe! The further you stick the nozzle in, the worse it is . What do you guys think, the vent valve? It has no emissions on it, side tank....

[Ronbo]

I think the pumps may have changed a bit. Forget the Stang and even on the Bronco I can't go full tilt. I dont put the nozzle all the way in and that helps some. I'm not sure if its the pressure/volume or just something as simple as the curve of the nozzle. You are not alone my freind

Modern pumps run way too fast. When I had the '83 it would take fuel so slow thet there was only one station here in town I could set the old pump on slow and it would fill without puking back.
One thing thet helps is to park on the side of a pump so fill tube is higher then the other side of the truck. Or just sit there and dribble it in very very slowly by hand. Also let the cap be off for two or three minunits befor filling.

at my work we have a 95 f150 w/ dual tanks the front tank you have to pump with it on the first notch of the pump, the rear tank is fine, it will take it as fast as you can pump it. never have felt like trying to fix it. we have a 93 gmc cube van thats the same way but i know exactly why it does, it has a kink in the fill hose. my suggestion would be to start there.

You have a fill vent tube from the tank to the top of the filler. I should have a rubber hose. Check to make sure that hose isn't crimped or obstructed.
Also the kickout on the nozzle is usually in the top and I find if I can wedge the gas nozzle to the top of the filler pipe that sometimes helps.

My '83 Bronco's rear springs are getting worn out, so I have a hard time putting gas in it now. There's a station down the road from me that has this steep hill next to the pump, I always park on that hill, so the front end is down and then I can fill it at full speed without any issues.

I drive my truck up a ramp placed on the rear tank side of my truck.

i saw a guy do that in a jeep wagoneer once...and got the idea i should do that in the wagoneer we were driving at the time (same problem) but i got the better idea of driving a reliable ol' ford not a POS.
[disclaimer] not all jeeps are POS's but this one was and wasn't reliable[/disclaimer]

as for the vent, this era of ford trucks have a plastic vent hose inside the filler neck. so it's harder to inspect. there's a fair chance it's damaged or disconnected, expecially if someone has removed the tank at some point in the truck's history.

the rear tank on my flatbed has a custom filler pipe, and i simply used a piece of 1/2" EMT for the vent pipe inside the filler pipe, because if fit the remaining piece of factory line perfectly.

See, that's the weird thing, I have a 66 Stang, and it will take fuel as fast as you can feed it! That's why the F150 perplexes me.

That, I was not aware of ! You could very well be right, as the truck had recently been repainted before I bought it. Thanks, Prankster...

Its obviously a venting problem, the trick is finding the bottleneck. It may be in a vent line, the vent valve itself, or something unexpected.

I found a mud dauber wasp had plugged vent hose on my truck. Still not sure how it got access, but it did very effective job of plugging things up and making it nearly impossible to fill the tank. Pure luck I finally found it. Hose must have been disconnected at some point and wasp thought it a good place to build a home.

I had this problem for four years with my Bronco, and it was the most ANNOYING thing about it. Sometimes, I'd honestly be at the gas station for 20 minutes filling it. Worse thing was, I had to stand there and monitor it the entire time or it would barf and spit gas back out, sometimes pretty viciously. I'm sure I looked pretty silly standing there for twenty minutes leaning partly over so I could listen to the gas filling. If it started changing pitch, I knew it was going to spit, and I'd stop.

Well, last summer, I got a hole in my gas tank and dropped the tank to take a look at it and patch it up. There's a plastic hose inside the filler pipe that vents air back out as you fill it, and there was a kink in it! Straightened it and have never had a problem since. I can put the nozzle in and fill at full speed and it hasn't spit out gas once.

If your gas tank is set up like the Bronco's, you don't need to drop your tank to get to this. Open the gas door and remove all the screws around the filler hole and loosen that up, then remove the hose clamp that holds the hose to the tank. The entire filler neck should come out and you can inspect, straighten, or replace as necessary. Hopefully it'll solve all your issues.

So, I took the filler pipe out the other day, and no plastic tube . There is just a metal "channel" on the interior of the pipe, and the metal flapper like you see on most old school vehicles. Wrong filler pipe? Missing the plastic tubing? Dunno....

[ordodraconis]

might be a good i dea to install a vent pipe system with all my trucks i had same problem and it was because of the vent tube.

That's exactly how mine was, but had the plastic vent tube. It may be missing, and causing your barf problems.

...and that could be whats causing my errant fuel level readings, if it fell in the tank and is impeding the travel of the float ......

on my 80' i have to hold the handle up so the nozzle is pointing down. it doesent have a problem when i do that.

Thank god my Mustang takes fuel faster than my Bronc does, because I have to fill it every day or two.

[sabre694]

I live in Oregon
The state doesn't think we are qualified to fill our own gas tanks!!! LOL
So i get to scare the crap out of the 17 yr old by yelling at him about gas on my paint and gonna call his boss!! LOL Yeah I know it's mean but the law is just stupid so it makes up for it

I hear some guys put the nozzel in upside down and that seems to help. I understand it there is a kink in your filler hose or vent tube. I was also told to make sure both filler and vent tubes are taped together with friction tap. I just put a new tank in my 77 f150 midship tank. I am working on the motor and have yet to put a drop of fuel in it, so I am hoping it works good!!
