The 7 psi Delphi and the 5 psi Carter, both put out 14 psi.
I have a Jegs, 4 1/2 to 9 psi, Holley style regulator set at just below 5 psi. When I turn the engine off, the pressure goes up to about 9. The carb doesn't leak and I never checked to see how long the pressure stays up.
The Carter guy made the claim that they are aware of the problem and are in the process of fixing the problem in all their mechanical pumps.

Damn you could run a tbi off of that pump. Thats crazy high for a carb. The off the shelf orielly special pump on my K20 has never given me any trouble, and im runny an eddy 1405 which is supposed to be just as picky as a quadrajet on fuel psi. seems pretty crazy to have a 5 lb pump pushing 14.
