Dual Gas tanks

[skimore11]

I have been thinking about summer trips and how far I can go. With gas often significantly more expensive the further from civilization you get. I don't like the idea of a tank in my truck bed.

 

My question is has anyone here put a second tank under there Comanche? Did you use one filler or two? How did you pipe and wire it?

I've thought about putting ax XJ or TJ/YJ tank under the back where the spare tires goes, but I have 10 gallons in the Gerry cans so it's less of a concern now.

I considered putting another stocker on the other side. It would be a VERY tight squeeze, as you'd probably have about 2" between them, and the pump/plubing sticks out a ways.

 

 

I'm not saying it's impossible, but it would be hard.

 

 

 

Jerry cans are easy...

I was afraid the space was too tight. Any ideas on other Wrangler tanks etc that might fit?

 

I checked out the wiring diagrams and did up what I would do for wiring. The ORG/BLK line is the existing power coming from the ignition.

X2 on the spare can. I carry 5 gallons with me if I'm doing other than around-town driving....you never know what's gonna happen :D

 

The old 5 ton wrecker I drove in the service (M543) had dual saddle tanks, but only one of them fed the engine. The other one held spare fuel and had a transfer pump on it that pumped fuel over to the main tank. The fuel gauge had dual pickups on it, and you could switch it to read either tank......when you saw the main getting low, you had to engage the transfer pump.

 

Not an ideal setup, but it would avoid you having to run a seperate filter and supply line to the engine. Just plumb it to dump into the main tank and use the already supplied factory hardware like normal :D The only thing you'd have to wire in would be the transfer pump.
