loosing fuel pressure:
Removed intake manifold to replace fuel pressure regulator: Existing regulator has no vacuum line attached to nipple. Manual says it should have one. Don't see any possible routing for vac line if it is missing. Has it been removed? Any ideas?
Also replaced fuel pump and now it is noisy in fuel tank, (maybe too much fuel returning to tank since no vacuum to pressure regulator). Maybe burst return line on pump assembly in tank. Sounds like it is pumping air or high pressure fuel through burst line iin tank.
have the same problem?
