Ok, here’s what I have. An old SX fuel systems 160 pump. I believe they were bought out by Edelbrock because their billet pumps look identical. I tested this pumps free flow at 2 gallon per minute. The pump out of the box was 12psi, but I turned it down years ago and now I read 6psi. While testing my combo on the freeway flat footing it for about 5 seconds in high gear I see it drops about 1.5 to 2 psi. Just thought I would bump it up a bit.
