How to test fuel pump/bypass relay

So, I poured some gas down the carb, started right up and died.

I have NO clue what fuse the fuel pump is on, we dont got the fuse cover and no google`in is helpin nor is the wiring diagram / FSM's

This is on a 79`SA

I'd be fine with bypassing the fuel pump anyway and ifnd the blown fuse or whatever.

Just check ALL of the fuses. Take each one and and verify that they are all working fine. If they are, check to see if your fuel filter is clogged. The fuel line that leads to the car, take it off and put a cup or container in it, do a light crank and see how much fuel comes out.

Oh alright.

Where would it be possible to get a cheap replacement pump?

The electrical was reversed and the car was turned on, blew alot of fuses, it prolly blew the fuel pump I'm sure.

Where's the fuel pump located, I went under the car and looked at the hatch under the carpet.

Any connector I can test it at without jacking it again?
