Electric fuel pump wiring
I always relay my electric pumps, so that's my #1.
I also get my engine cranking before I flick my ignition switch on my dart, but I'm locked at 40 degrees.
Also allows me to crank w/o full fuel flow if say...it flooded. Or...run the pump to set floats or adjust fuel pressure.
If it was a 318 on pump gas with a little holley red....there is no harm in doing it your way.
