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.
