Thanks all for your help. took the fuel line off at the mech pump 123 sec. to pump 1 gal of fuel.Looked in the fuel fill neck slow steady flow, not squirting.The restrictor is in the banjo bolt .Now waiting for a new fuel pressure gauge that I can install permanently.Will let you know results.

Look at page 46-09 step 9, the orifice should be removed from the banjo bolt. Having the orifice in will cause your low fuel press indication.

Mike,

It's been a while since I messed with this, but as I recall the restrictor orifice for the return line is not the pilot jet. The restricting orifice is not accessible without physically removing the return line from the manifold block. That's why the blow test is used to verify the configuration.
