I bit the bullet and bought a new tank for the truck. I had Sandy pick up the old one and because the new truck is a crew cab, there’s just less room from the front wall of the bed to the wheel rise. This tank will give me 60 gallons but I loose the toolbox and pump. But since it’s diesel I don’t need the pump and can let the fuel gravity feed from the upper tank to the truck tank.

So the idea here is going to be to tie into the auxiliary panel in the cab so that (in theory) I should be able to pull over, push a button, and watch the onboard fuel tank fill up. But I’m looking at solenoids and the standard 3/8 NTP only allows for a .6 GPM flow, it looks like the 1/2 offers 4.6 which would be bare minimum.
