fuel pressure numbers with Holly Red inline with stock LP
Wanted to check and see if the following numbers are OK -- won't blow the seals in the VP44 injection pump. Measuring from the Schrader valve on the VP44:
Before Holly Red:
15 psi idle
12 cruise
9 wot
After Holly Red:
21 psi idle
18 cruise
15 wot
Third LP in 25K miles, so I hope this solves it. Btw -- LP only develops 4 psi at idle through the Holly, when it's not on.
Those numbers OK for the VP44? Thanks.

Those numbers should be fine. Make sure you do not lose them over time, and drop too much (under 10 psi at any point). I have no experience with the Holley red, what are the specs? I have a brand new Holley Black, a warranty for a leaky pump. It was always lower psi than my Carter, and cost double the money. .........................................LE
