I thought that maybe this one gas station had weird pumps, but every time I fill my Fiero, gasoline squirts out the fill hole like the nozzle didn't shut off in time. Anybody else have this problem? Is there any way to correct it?

They have a smaller neck to start with, and could be some of your vent hoses are plugged partially. Check for those problems or just dont click the pump on wide open.

You have an '87... so you have the expansion tank in the cavity behind the passenger seat. If you take off the right rear tire and the forward wheel liner, you will see the fuel vent lines running to the bottom of the expansion tank. I bet your lines are either badly corroded or have dissolved altogether. There are two steel lines that pass under the battery tray and along the firewall to the back of the fuel tank. One of the lines connects to the vent from the tank and the other connects to a line that goes up to the filler neck. The fuel station pump is not sensing the increase in air pressure as the fuel backs up into the filler tube and therefore is not shutting off. Mine wasn't too difficult to fix because I had the exhaust and AC compressor off, the battery out and the car up on a lift.

Good luck,
- Jimmy

Good to know. I always have that problem at certain stations that fill faster. For some reason pumps tend to be much faster in NH than VT.

Guess I've never noticed any of that. Does anybody have a pick of what I should be looking for? If a line has 'dissolved', will there be a fuel smell or any danger because of it?

Gas station fuel pumps click off when an increase of vacuum is sensed in a secondary tube....next to the station filler tube. It will suck air until the fuel gets high enough, and when it starts sucking fuel, the pump shuts off. The usual reason for spillage is that the gas pump handle is not straight, or all the way in the car filler tube. I am not sure how the expansion tank would contribute to the problem. Is your overflow on the outside of the car or somewhere else?

I've had it happen to me a handful of times, the first time I didn't know about it I had at least a half gallon spill out as I had set the pump handle to go on its own and it was splashing out as I was standing a few feet away before I noticed.

It always spits right back out the filler tube from what I can tell. It does click off, but it probably splashes about a cup of gas before it's finished.

I have pictures in my phone. I'll try to get them loaded in the next day or two.
