Electric fuel pumps are dangerous .

In addition I use it to control power to the air bag compressor via a 40 amp relay. With the compressor and fuel pump married together they will run briefly then shut off, if I pause the key in the run position before engaging the starter. I can then start the engine without the compressor drawing current from the battery while cranking

I use this same controller. It will make your fuel pump do exactly as it does in todays car/trucks. If in a wreck and the engine died the controller shuts off the pump. You can use it for fuel injection or carb. If you got the key on listening to tunes your fuel pump isnt running.
