Shield / Shielded wire

[dhutton]

I have never used coaxial cable for a pwm controlled fuel pump in several builds. It seems a little like overkill. If you’re really worried about radiated emissions from the fuel pump wiring you could use twisted pair for the power and ground feeds to the fuel pump.

I would have guessed conducted emissions from the fuel pump are a bigger concern but I’m getting rusty in my old age….
