out the filler neck where the nozzle goes in???

that's odd indeed....

i suspect you might have a leak in the neck but i'll let the experts chime in. or you have poor gas station service in your area. if memory serves

Have your 'representatives' forced new nozzles down your throat?

Out here in MexiFornia, the POS Air Resources Board has forced a new generation of vapor-recovery nozzles on us that not only added 10 cents/gallon to the price, but the damned things are so FUBAR that they had to remove the lock-on clips from them because they can cause overflows and fires...

Typical: Vapor-recovery nozzles that cause more overflows than the old, paid-for ones... clap

I must mention my fuel gauge is not working properly. My dad replaced the fuel pump and i think he forgot to put the float all the way down because when it is full it is at 1/4 and then it drops down to e after a little while and stays there. Then when i fill it up again it goes back to 1/4 so i will tear that apart next week to see if that is the problem with the gauge but i really want to find out about the gas shooting out cause it is gonna get paint in two weeks and i dont want gas to get on my brand new custom paint job!

Uh, you didn't drop the tank to do that fuel pump job, did you ?

I only ask because the tank has a ball-valve to prevent overflow into the vent-circuit... But if you only removed the "fuel-module" via the panel in the trunk, then it shouldn't apply.

It sounds like your EVAP Vent System is clogged/frozen/stuck/inop. If the system is closed all the time, the tank will build pressure, especially when filling up, causing the fuel puke. I would have the EVAP system tested for function.

As for the fuel gauge, did your dad replace the whole unit or did he simply replace the pump itself?

My FSM says that when doing any work on the fuel system, the fuel pressure should be eliminated first, any chance you guys didn't do that when replacing the fuel pump?

how do you test the EVAP system?

As for the fuel pump. Is the sending unit on the pump or not if so we took the whole pump assembly with everything attached out of one of the parts cars and put it in my car

There is a pressure relief valve on the fuel rail, similar to that on a tire. Cover the valve with shop towels and depress the valve to release pressure.
