The relay switch for the back fuel pump for my 1984 Pace Arrow rv does not work. I'm trying to find this part number but I am having no luck. Suggestions on where to get this ? #0332014150

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.

If the oil pressure switch has two wires on it it may be one that shuts down the pump. I'm not positive but I think it completes a ground circuit, not the hot side though (but may run through a relay.) There should be a pump relay under the hood with a group of other relays. I don't have a wiring diagram for your car but you can get a basic diagram in most inexpensive manuals. They wont usually give you locations but at least you can get an idea of how the system works. There usually is a fuse. If the fuse block is not labeled, use a test light and probe the back of every fuse for power with the key on (takes about ten minutes and faster than trying to find info) change any that are blown. The most likely culprit is a relay, so after testing fuses look for it. (usually on drivers fender or on right side near firewall.) Worst case, trace the power lead all the way through the harness 'till you find where power begins.Testing is important here...I could give you much better info if I was there to do it for you. Most important is to stay "on track" till you find the place where power ends. Don't jump all over the place or you will end up doing an incomplete test.

I would take another look at how the two batteries are connected to one another. Here is a schematic to go by

The in-tank pump does run constantly. The outer pump is the one that is switched. I'd suggest that you rewire properly, as using a jumper will cause you more headaches.
