Fuel Pump Relay for 1980 to 199* P30
I found another maker for the FPR used in 0lder P30's, it is Airtex and the part number is 1R1240. It is an exact replacement for the OEM, TRW 15528707 relay. Best part is the prices range from $1...

Yo! Bud! I was sure glad to be sitting when I clicked on the O'Reilly link and saw $120!!!
Believe I'd be getting a Bosch Relay and Socket
Just have to be a little careful. There seem to be "Bosch" Relays with only 4 contacts, meaning no "back" contact closing an alternative circuit when the relay is NOT energized. OK to use only 4 pins of a 5-pin relay so long as the back contact isn't needed. OP's diagram says it IS needed.
We found where some of the later Workhorse Class A chassis used a "Siemens Relay" that does the same thing but in a different form factor. Carried GM part numbers.
Would still like to know more about the "regulator."
