Oldsmobile/Buick Repair: SMELL, purge valve, seat van

Question
I have a 94 buick skylard and I smell fuel in side the cab I have looked for leaks and have found none

Answer
Hello Ernest,
I haven't seen that car for that problem, but some things I would check for are a saturated vapor recovery canister, which has just absorbed all it can, and possibly the vapor purge valve is not operating to draw the vavors into the engine and burn them.
Check the hoses to it, and there is probably an electric control valve in one of the hoses. make sure it is working.
The filler neck hose at the tank deserves checking. it can allow gas to leak out on top of the tank, and then the fumes can get in through window/door seals, or the trunk area through the back seat.
