Auxiliary fuel tanks as primary source.

here's some background. My k-20 is getting an LS engine. It's also getting a rear facing PTO. Now then, it's currently setup with saddle tanks that are going to severely limit dragging the frame over things should the need arise. Also the service bed I am planning to use make them a no-go. Now I can't put it in the back of the frame as that is where the winch will reside. So I have done some searching and I found an aux. tank that is the exact dimensions of the width of the bed inside. Since it is a new tank, I am thinking I can pull the front wall of the service bed, weld in the 100 gallon tank and rock on with my other business. The tank I am looking at will be top filling but has two threaded bungs on the bottom for fuel lines. It also have a fixture for a level sending unit. For PC the tank is 1/8" wall thickness and DOT rated to haul fuel.

Anything I am missing?

Sending unit? And are you running a frame pump?

Yes and yes. the tank I am looking at has a sending unit installed and I was already planning to run an inline fuel pump for the LS engine.

Just vent and return. I’d have some concerns with slosh and keeping the bung hole wet

Snicker........bunghole. ANYWAY... It has baffles in it and I was planning to stuff it with fuel foam to nullify any sloshing. Now keeping the bunghole wet (snicker) I'm not sure about that.

Do not use foam. You will regret it. Quickly.

Since the tank will be new, I guess I could weld in a dropped portion for the feed line.

The tank I am looking at is actually rated for gas so it is appropriately baffled, vented, has a fuel line and return line plumbing as well as a sending unit for a fuel guage. I had to look for a while to find a steel one, most are aluminum. According to the DOT regs as long as it's under 50 gallons I won't need any additional placards for anything for it either. This tank is DOT approved for this purpose.

You may regret welding the tank in if a leak develops later on down the road...I'd make it a bolt in deal instead..

I'll see what I see when I actually get it here. I need as much of my bed as possible so the plan was to remove the front section of the bed to push it all the way forward. May be possible to bolt it in there. I don't know yet.
