run a can of gas up front in the engine bay or front pass floorboard to the pump inlet with a 5/16 neoprene hose & take it back it back out. this'll tell you if the prob is rearward from the pump or if it is the pump or pushrod. EDIT What Supercuda said, check that out first (the venting). MORE EDIT leave the cap loose or even off (wont hurt you for a quick test) & (re)try it
