Hmmm...... I have no idea what it's called but there's a little hinged flap that stays shut unless you insert the gas nozzle.... maybe this is failing somehow and not containing the pressure in the system?

 

there is no charcoal canister we pluged it but we where thinking that was it but we unpluged it and it still happens

 

that thing you plugged coming out of the firewall for the charcoal canister is suppost to be a vent, route a hose that goes fromthat to where the charcoal canister vented to its right under your shock tower thers ahole

 

yes i know it is not pluged now and it still sprays fuel out the gas cap

 

Mine does this too! My charcoal canister is still in the car though. I know the pressure isn't supposed to be that much but I don't know what to do about it.
