Re: another fuel lift pump question....
I am smiling from ear to ear. Why the heck did I keep thinking in series wiring? You are absolutely right, just wire it in parallel and allow the pump motor switch to complete the circuit!!!!!
I will run a wee bulb and waterproof lens into the footwell bulkhead, or an LED into the instrument mount. It may get a wee bit annoying at night, as it will have to be seen during the day and at night, but it's better than a lost motor.
I used an electric pump on an engine conversion, ran for years full time, no problems. You could just remove the mechanical pump and carry a spare electric pump. More on pump setups:
