electric fuel pump circuit

Here is how I did mine. Sorry about the quality of the drawing.
The oil pressure switch is a SPDT(single pole, double throw). The common is grounded. With no oil pressure the dash light turns on. With oil pressure and the dash switch in the on position, the relay/fuel pump turns on.

Also, with no oil pressure(engine off) and the dash switch in the on position, I can press the override button to momentarily turn on the pump.

Note that this is probably only suited for carbed engines since the relay/pump won't turn on for a few seconds after the engine has started.

I'm not trying to confuse anyone. Just showing a slightly different variation.

Thanks ang94541

So you got the fuel pump set to go after the oil pressure switch is thrown, but u can still prime the fuel system with the override button before cranking yeah??
