[QUOTE="machoheadgames, post: 438219, member: 18789"] Hmm. The pressure should definitely be 31 with vac connected and 39 disconnected. Since it is not reaching above 25 psi, I would say the fuel pump is weak. However, with the pressure going up to 35 with engine off, that doesn't really make sense. I'm not sure how the pressure could be rising like that. [/QUOTE]
