Stock fuel pressure?
What is the stock setting for a 454 mag efi GEN V? I have a 454 mag,with 502 injection, with 500 efi cam, and gil exhaust and it runs so rich I can't keep plugs in it?

As per Merc Service Manual #16...
"With the engine running and the regulator vacuum line disconnected, fuel psi at the pressure test connection should be 34-38psi. If the pressure is too low, poor engine performance can result."
