Just about any 12 volt relay will do. A fuel pump is a low current device. It does not have any high current start up requirements. My Cater P4070 draws less than 2 amps. I have a 3 amp fuse in line with it and have never blown it. I'm not quite sure of your wiring set up, but you can always go to the junk yard and get a few relays out of GM vehicles (or other brands) and wire one up with some small push on connectors.
