Location fuel pump relay

Need to find the location of the fuel pump "Relay" so I can eliminate it before changing he fuel pump. Engine will run if I squirt gas in Carb. I found 3 relays side by side all with same p/n on driver side wheel-well. Found another under a plastic panel on the passenger side firewall.

That one has a different p/n than the others. I'll get some one to turn the ignition and see if I can feel any of them engage, but I still don't know which one is the actual Fuel Pump Relay. Other functions may be happening to the other relays simultaneously. It would really help to narrow it down.
