Looking at a RDS aux tank/toolbox combo for my 2001 GMC "gas" truck. Why is there no transfer install kits for gas engines? How would you get the fuel from the aux tank to the main tank while underway? Years ago I had a aux tank in an old farm truck and it was connected to the fill pipe of the main tank and you never had to remove the factory tank fill cap to put gas in you just filled the aux tank. Cant the new style trucks operate that way?

I bought a 45 gallon aux/tool box tank for the same truck you have from American Tank, in Dallas, TX...Also Transfer Flow offered the same set up.. Both were pricy but I felt well worth the money. My tank actually did not transfer but was switched back and forth with the main tank. Operated jus like the old duel tanks of the 70s. Might check with either of these companies for additional info. The units were both EPA approved. Maybe not so now..Good luck

I just use a 114 gallon aluminum fuel tank from a dump truck. Paid $150 and it sits in/on a rack in the bed of my truck and is plumbed into the filler tube and operasted via an on/off manual valve. Works for me.

So the tank you bought has a fuel pump inside of it? I'm confused on how you switch back and forth between tanks with this setup?? Keep in mind that my truck is a GAS truck not diesel. I dont think the diesels have the pump in the tank.

My thought is: no aftermarket tank manufacture wants to be sued for having a vehicle explode. Gasoline is way more dangerous than diesel. Explosive Vs. Combustable

I had a 50 gal. aux. tank installed in the bed also. to transfer fuel you turn on a switch on the dash. The fuel transfers from the bed tank to your original truck tank. You can't run off the in-bed tank, only refill your tank that came with the truck. One downside is the switch on the dash doesn't know if the tank is full and will run fuel out the filler cap happily.

No, that's not it. The vapor in a gasoline tank is too rich to burn. The vapor in a diesel tank is too lean to burn. Either will burn when spilled in a wreck and exposed to an ignition source. The gasoline is just easier to light due to its lower flash point.
The reason you don't see aftermarket gasoline tanks is the current emission control logic tests the tank for leaks by subjecting them to a vacuum or some other method. If the tank is bigger than the test logic allows it shows up as a leaker.

The external tank had a fuel pump and a fuel gauge internally. The transfer switch was installed in the main fuel line just fore of the main tank. A switch on the dash would transfer tanks and also the fuel gauge.
