Electric fuel pump
I'm going to install an electric fuel pump on another of my old vehicles. I've read somewhere the what it should be wired in is with an oil pressure switch wired into the circuit so if for some reason you're vehicle's engine is stalled like in an accident or roll over as soon as the engine dies the pump stops. Sounds like a good idea to me but maybe some of you guys have a better idea.

That is standard practice to place an oil pressure AND an internal switch in series with the fuel pump (with a starter override).
Also, don't put an electric fuel pump inline with a mechanical pump as that provides potential pathways for gasoline to be pumped into the crankcase.

oil pressure switch and a inertia switch too, Bob. I've got the parts gathered for mine but haven't had time to do it. I'm gonna have to put a tee in the oil pressure port on the back of the block so I can have oil pressure on dash and the kill switch for the pump. Sniper has the wiring diagrams on their web site.
