Ok, then I would be looking for a gas leak on the suction side of the
fuel pump. I usually see the leak where the rubber hoses attach to the metal tubes along the frame rails either at the front or rear. I am thinking front on yours. Check the return line up front for leaks. Same place where the rubber meets.
