I know in my buick there are these plastic union fittings on the gas lines right above center of motor. I pushed one aside one day and gas spit out. Maybe the gas is coming from there. My car will start and die right away if I have a very low tank. Gonna change the fuel filter and them fittings when I get a chance. Also was thinking of changing the M.A.F. sensor too and even the EGR valve but they want 160 bucks for it and moneys tight.
