They claim it maxes out at 6.5 psi and since Edelbrock doesn't recommend going over 6.5psi I thought it would work. I have a Vacuum gauge that says it can test fuel pressure. How can I use this? Just push the end of the gauge's hose into the outlet hose on the pump and clamp it?
yes, i have the same pump for all my edelbrocks and have no problems. i put the gauge on the end of the fuel line an crank it over an they read 5 to 5.5 psi. i buy the pump listed for a 1970 camaro with 307 2 barrel, they are rated at 5 psi.
if your pump reads 5 or 5.5 psi then id say your float drop and level need adjusted. just about everyone ive bought new needed it done.
