Hi ya'll, been meaning to bounce this one around and filling up tonight reminded me.<br> I can't put fuel in at the full flow of the pump; it keeps backing up in the filler neck. Happens every time I fuel up, with high flow pumps or little ones at car places. Kind of a hassle, tough to tell when it's really full.<br> Anyone else have this and how did you solve it if so?<br><br> Thanks,<br> Rob

Mine does the same thing if I stuff the nozzle all the way in. I usually have to have it pulled out part way to get full flow into the tank. <br><br>Careful though so you don’t get fuel rushing back out before it turns off. :o<br>

Sounds like you've got something in the way. I can use the high flow pumps at full throttle in my 99. I usually only open them half way do to the fact that the fuel will get lots of foam on top and you can't get as much fuel in the tank.<br><br>Might want to check the filler neck to see if it's kinked or maybe the anti syphn thingy (not sure what you call it) is messed up.<br><br>DB

With that new flat on my truck, I have to watch how fast I pump mine in, The first time I filled it up fuel ran all over the place. The way mine is piped with the flat is not the best way, but the guy did it the best he could. I have to fill up at Southern States which has a platform for trucks with flats thats drive over this platform and it rasies the driver side up about a foot and so the fuel runs striaght down into the tank

You may have a restriction in the filler neck. Mine will take it on full but causes to much foaming. I put the nozzle in about half way and pump the fuel on low. After it shuts off, I can still get more fuel in the tank.

I do the same thing Huey. The foam is really a pain. Check the overfill line. it is an air duct. If it is kincked it will cause this to happen.

Isn't there a ball in the filler neck to prevent fuel from spilling out if the truck is overturned?<br><br>Maybe the ball is stuck in the &quot;up&quot; position, or just hung up on something and moving slowly?<br><br>Just a thought.<br><br>I've never had a problem, but haven't even had the truck a year yet.<br><br><br>phox
