Is the relay sticking? How about the auxillliary oil presure switch?

If either of those are sticking, the pump will run continuously. Of course, the pump SHOULD run continuously whenver the engine is running and creating distributor reference pulses.

Sounds like the pump was dummy rigged and you get to mess with the end results.

I suggest going over your entire pump wiring and find out what's all wired to what. Grab a fuel pump schematic from Trickster and rewire as you need.

I have mine wired through a generic 30a relay from radio shack.
