Priming the carb
My rig is on a John Deere chassis with a carbureted Ford 460. The fuel pump is wired through an oil pressure switch as a safety feature; no oil pressure, no gas. I've been thinking of wiring a mom...

Follow straight down from the Starter Relay (fender mounted solenoid) through the Diode to the Tank Select Switch. The not-so-good idea was that the Fuel Pump gets powered up when the starter is engaged. That's not very good because you want the carb primed BEFORE you crank it. Besides, the cranking sucks the voltage down so the pump isn't as effective as it should be.
A pushbutton switch is the hot setup.
I used to lift the hood, pull the Blue wire off the Starter Relay and hold it to the Positive Battery Terminal to run the pump. Switch is much better, particularly in say the Dark, the Rain.
