babybaluga32 Posted May 6, 2011 Share Posted May 6, 2011 This is a totally retarded post, but I want to know.. EVERYBODY tells me it is around 40-45 psi, but my manual says 28-32psi @ idle. At 35 my plugs foul like crazy. Stock fuel pressure should be 43.5 psi with the vac line off of the regulator. ^ I think* that guy knows what he is talking about. Its sure seems like it with everything else, but idk. My stock fpr which I have always thought was broken idled around 40psi, but every other one I have swapped on was around 25-30psi at idle.
