I could use some advice on a few electrical items.

1. The motor is out of a 91 Camaro and it has an electric oil pressure sensor next to the HEI. I believe the 78 was mechanical oil pressure. What are my options? (see question 2 first)

2. I am using an in tank electric fuel pump. Without an ECM to prime the pump, how do I set up a relay to the pump. I would like to incorporate the oil pressure sensor to control the fuel pump relay? Do I need two relays? One to prime and one to run?

Anyone recognize one of these part numbers for the oil pressure switch to operate the fuel pump relay?
OEM Part Number(s): 12353898, 1S6812, 2011345, 25036845, 25036938, 6000092, PS215
