Hi all. 2007 5.4 Screw.

When filling at the pumps, I cannot run the nozzle any faster than a moderate trickle, and it wants to click off. I get that backpressure "sighing" noise that rises up the filler neck, and I need to stop the nozzle for a bit. Sure takes a long time to fill at that rate. Is there maybe a vent that could be plugged on the filler neck or something? I also notice, with the GM's I have had in the past, there is a brass colored flap at the inlet; on my f150 it is not there. Is this normal?

No brass plate is normal. My moms old Isuzu Rodeo had one but my F150 does not so I think your good there. Couldnt tell you why your gas is slow though. Good luck

I'd have to look at the EVAP system but on the systems I get to screw with, slow fill = vent solenoid or it's filter is clogged. USUALLY its a cobweb though There may be a tube running alongside the fillerneck. Follow it back to the first connection you can get to and blow air though the part that goes up the filler neck. I'll look tomorrow and see how the system is on these trucks, it may be different.

I get a similar issue if I don't insert the pump all the way to the rubber splash ring. Anything less and it'll kick itself off with more than 1/3 flow rate.

Does it happen at different gas stations? I've had all kinds of issues at different pumps...slow fill due to low pump pressure, overflows where the pump doesn't sense the tank/filler neck full and pours gas all over the truck and ground, high pressure pump settings where the thing shuts off as soon as it starts to pump gas...

I have had this issue with mine too. When this happens to me, I normally have the nozzle inserted all the way in and I simply pull it out about a half inch or so. It doesn't happen at all gas stations so I'm guessing it has something to due with the curvature of the nozzle. Might be worth a shot if you haven't tried this already.

If you haven't already tried another pump or different station, I'd try that. My old Mercury would do that but only at certain gas stations around the area. I always thought it had something to do with the angle on the nozzle being a little bit different..

When in doubt... pull it out! Haha!

Man... That one happens all the time for me if I'm not careful. Damn annoying. I figured it was just me because my body lift changed the pipe angle some. I've never had the same issue with any of our other vehicles.

Does it harm anything overflowing the tank that way. I have done this twice in the past 14 months.
