Is 42-44 psi at idle and unplugged 49psi unplugged OK for my Lb9?

Re: Fuel pressure

The factory spec is 42-45 full, 35-38 with vacuum. It's a little high, but should run acceptably at your pressures.

Re: Fuel pressure

At that time, injectors were flow-spec'ed at 43 PSI, so you're right where you should be.
