aux fuel tank in truck questions
SO i have a camper shell on my 2003 f250 SD diesel (7.3L) and was looking at putting a tank in bed, 37 gallon, and was wondering how to get fuel to main tank. The tank has 2- 2" fitting one with a...

I've made two of them with my dad. 1 for a F450 he had with a 'hauler' style bed, so it was a custom fit. 1 for his 2nd gen.
The 'out' side is located on the driver's side of the tank, and pushes toward the rear of the truck along the bed side. A small nipple to a ball valve, so that the tank can be isolated because of a leak, or to remove the tank for any reason. After the ball valve there is an elbow and turns to rubber line that goes the the bed floor, and is protected using a chase-nipple (smooth radius electrical fitting). Goes through an inline fuel filter, then a 12V solenoid operated valve (aftermarket $25 fuel tank selector valve), then a high volume low pressure fuel pump. The tank is piped to a fitting that we welded to the metal part of the filler neck.
Keyed source toggle switch on dash energizes the selector valve and pump at same time to pump fuel from the aux to the main tank. Gravity feed was too slow so he added the pump.
Here is a link to the increased cost of the selector valve used. You will need to plug up one of the inlet ports (normally open port) so that junk doesn't get inside it.

Since you have a camper shell, here is a link to a guy that has one under a shell.
