Transfer tank for a e350

[silvrzuki77]

Hey everyone, so I have a Ujoint converted 2009 E350 RB. I tow a Offroad tent trailer I built with airbag and 35's so it's not the most fuel efficient rig.

My plan is to use a 80's Chevy suburban 31 gallon tank and pump where my spare tire was after I cut the cross member out. Suburban tank is the perfect dimension and the fuel filler points right at the middle of my bumper so I can fab a rear fill mount pretty easy.

My stock e350 tank has a unused port on top that I plan to run the transfer tank to.
Obviously I will need to do some wiring and figure out a fuel gauge level.

I know ford had aft tanks for RV and Uhaul but so far super expensive to source.

Anything I'm missing that you guys can thing or can cause problems?

Here's the tank I'm thinking of using.

Just make sure the tank is properly vented. I came across this video doing my own research. It makes sense to be careful how you introduce fuel into the main tank. https://www.youtube.com/watch?v=dP6Pogm6Ts0

Why not just get an E350 aft axle tank pump complete and drop it into that tank. I would think you could just extend your wiring from the main one or source the switch and wiring for an aux tank from Transferflow or the like.

The pumps aren't that bad, you'd have to fab a flange though:
