Ok so I got the new pump on the car with reg. and plumbed it all, which didn't take much. It was pretty much a throw on, only had to change one fitting.. My question is that when I set the pressure I set it running and was at 6.5 lbs. I shut the car off and then had to start it later in the night and the pressure was a hair under 6 lbs .. why the change.. I'm going to re-set it tonight when I do the valves.

I had the same problem and it ended up being my liquid filled gauge. Once the car warmed up the pressure would drop like from 6.5 to 3. I ordered a new non liquid gauge and haven't had a problem since.

When you say it was 6 was that what the gauge showed
before you turned the pump on or after you turned
it on

Mine isn't liquid filled. It was working fine with the holley blue pump, but now it seems to creep on me..
