fuel coming from vent canister.when removing gas cap,I have a'lot of pressure.It acted like it was bucking. Tthanks

 

Driving then car began to buck. parked in drive way and noticed fuel coming out of vent canister. opened gas cap to releave the pressure, it had alot of pressure. thanks to any suggestions!

 

Well your probably going to be told to do a fuel leakdown test. But if it was me and it had been awhile since I changed the fuel filter, I'd probably do that first. Strikes me that something is clogged and since fuel filters get clogged, eh, why not change it? Something that should be changed after certain period of time\miles anyway.

 

changed it with ac dellco,about 5 fill ups ago.Also replaced the vent canister after that still the same..the gas cap has alot of pressure,when i open it to stop the fuel leak. Thanks for the reply..
