Has anybody ran dual tanks on these trucks before? I am thinking of getting a burb tank to go where my spare is suppose to go. Anyone done this yet? I'm just tired of filling my truck up every 200 miles.

Haven't seen it done but I would imagine that it has been done a time or two. I'd love to get an extra tank on my burb for long drive or even a smaller second tank for backup while on backroads

I was actually thinking about doing this too. Since my truck will be 3/4, I would like a bigger tank to last me longer, than my little 25 gal, whereas the tonners and 3/4 got a 35 gal. I have a Burb just sitting out in my yard and has the fuel tank. This would be better than me finding a 8 bolt rim and 265/75 tire to go in there. If someone knows how to do this, please let us know!!! :D

the factory dual tank setups on the 96+ cab and chassis trucks pumped from the aux. into the main, and did not switch. they had a little control box that activated the transfer pump when needed, and averaged the fuel level signals to the dash guage (one full,oneempty,averaged to half full on guage)

I have long thought about putting a burb tank in place of the spare, but on another forum, someone else did, and said some cutting and modifying was needed. I like the warm fuzzy feeling of bolt in, so I decided not to do it. plus, I run the 6.5L diesel, so even loaded I can get 300+ per tank, and in bed aux. tank are OK since diesel is not explosive.

I've seen people do this to relocate the tank. For a shortbed you're stuck with the smaller hoe tank and a lingbed will accomodate the burb tank. I'd love to do this but then where do I put my spare?

What if I ran the same setup as the older gm trucks that had a switch that swapped between the tanks?

So my truck being a short bed would only allow me to fit the 30 gal Tahoe tank? Is the bed being longer behind the axle the reason why the suburban tank won't my short truck?
