Yep, that is a head scratcher!
Yes, for now it’s wired to a rocker (our cargo light rocker worked nicely) and it will be on an ignition circuit. Had to hurry and button up the truck so I’ll have to come back to the wiring after the bed replacement but it is functional, just not idiot proofed yet! Thinking about a relay using the electric fans 12v ign trigger so if the fans have an issue the pump won’t work also.
Downside? An additional safety feature is a pressure switch, no oil pressure no fuel pump deal (see diagram). Some folks don’t like the noise of an internal/external electric pump, these are fairly quiet as they are insulated against the mounting bracket (I do like to turn mine off if it’s not needed, hot days and cheap gas just don’t mix). They are an inexpensive pump and I wouldn’t buy the knock off’s get an actual Carter brand if you’re going down this road.

Very good news on the new bed though. Have a Happy Thanksgiving Brett! |
Happy Thanksgiving Ryan! I’d assumed diesel fuel pressures were much higher than these things can produce? I do know a guy who runs a small fleet of classic carbureted cars running E10 fuel and no mechanical pumps just these low-pressure pumps. He’s got one that’s a little finicky that he uses to drain tanks/move fluids (I’ve borrowed it now and again also) for 20 years. Since we are running one on each truck I did get an extra for the shelf so I guess my borrowing days are over…
