Refueling problems

I'm not sure which forum to put this, but I'll try here.

I can't take filling up my daily driver anymore ('94 Ford Probe GT). Everytime I try to add gas, the lever on the pump handle 'pops' as if the tank is full. But it isn't. What's going on?!?!? It takes me like 5+ minutes to fill up, because I have to continually pump the handle lever. Or I can try to hold the lever at the point where fuel literally is pumping as slow as the pump will allow.

How does the pump determine when a tank is full and 'pops' the handle lever? I would think maybe pressure or something. But that wouldn't seem to account for the fact that pumping fuel at even a trickle will 'pop' the handle. That much flow rate couldn't generate any pressure. So what the HECK is going on here!?!?!?

Its only a matter of time before someone punches me for hogging the pumps.

Thanks

Your tank is not venting out the air quickly enough. There is usually a vent hose that runs down beside the filler tube. It's probably plugged.

Well, I'll look for it and try to check it out, but that seems odd. Even if I pump about as slow I can (OK, a fraction above the absolute minimum), it still pops. That much air should vent around the nozzle with no trouble.

try different gas stations

The pump nozel is angled differently on different pump handles. My Riv does this at BP and one of the local cheap stations. I think there is splash back that shuts off the pump.

yeah the pumps will shut off whenever gas hits the nozzles so if it splashes back the pump shuts off. sometimes if you pull the nozzle out a little bit it goes longer

I normally hook the gas hose around my driver side mirror so it puts the pump nozzle at an angle while keeping it slightly out so it vents properly.

I tried another station with no luck. Maybe I should try a few more. I also tried pulling the nozzle almost all the way out. And I've turned the nozzle to pretty much upside down. Nothing seems to help.

If its really a vent issue, and I try to fill up from a 5 gallon gas can, would I notice the fuel going in slowly? Or would it possibly spill out around the filler neck if the tank can't vent fast enough? I'm hoping to get a clue from trying that.

I took part of the vent line off and checked it, and it seemed OK. I can't get to the entire thing unless I drop the tank. I'm very curious to find out the problem, but I'm not sure I want to go that far.

Thanks
