    My '87 was set up with a Carter Comp. AFB plumbed to the in-tank EFI pump. The carb has an inline regulator which appears to be plumbed into a return line.

    The regulator spikes to 7 psi after ignition on and then jumps back to ~4 repeatedly.

    Q: It seems like I need to adjust the regulator down more or check the return for obstructions. Any suggestions?

    If yur not having problems with it. I think you should leave that set up alone. Or replace it with a inline pump meant to be used for a carb.
