Relay required for a fuel pump kill switch?
Wondering if a heavy duty switch will suffice instead of having to wire in a relay? Recommended amperage?

You need to know how much current the fuel pump draws. Depending on that, you choose the switch rating and go over by a 20% safety margin. Although, it is a better idea to run a relay and requiring a smaller switch.
