Now Im starting to wonder if my other one is bad as well. Karl, do you know if they have a built in check? Im getting drain back or siphoning. At least that is what I think is happening... My fuel pressure gauge drops pressure rapidly as soon as the car is shut off and goes negative.

On Chuck's pump, it wouldn't pump enough fuel. We disconnected the line after the pump and had it drain into a jar while cranking it over, and nothing came out. I went home and brought a couple of used ones from engine cores I have laying around and the first one worked and we got fuel to the carb...

Then we had to get the secondary vent to stop spouting fuel.....
