Hmmm...fuel pressure should drop significantly at idle...36psi is ok with FPR vacuum disconnected but should drop to 20 or so with vacuum line disconnected.


34 psi at idle is fine.

Should rise to 43.5 with vac hose off and plugger.

With atmospher (no vacuum) on FPR, it's like WOT, so pressure goes UP about 9 psi.

B230 FP should never go to 20 psi.
