Default Re: fuel pressure (88 ragtop vette)

Mine is at 44psi key on engine off. It drops to 39psi w/engine running idle.

I don't know if this is normal or not. I believe the manual says ... hold on let me get the manual.

Okay now I need someone to teach me how to use this flipping manual!!!!

It says "see chart in section A-7." I don't see a section A,B,C,D..... of any other lettered sections only numbered! :mad

Default Re: fuel pressure (Midnite 88)

Okay, here it is directly from the manual.

Fuel pressure, with pump running should be 40.5-47psi.

Start and idle engine at normal operating temp pressure should be lower by 3-10psi. :crazy:

That was almost too much work.

Hope it helps.

If you need, let me know and I'll scan and E-mail you this page.

Mike.
