Xtra fuel tank
I checked out the fuel tanks on that store. They had tanks for 1500 and 2500 but none for a 3500. It is pretty tight where my tank is. I don't see how I would put a bigger tank their but I could be wrong.
basilkies..... I have a 1-ton flat bed and I made a dump bed with a scissor lift from an older truck. All that junk takes up alot of space. But I still have the big space behind the rear axle for the xtra tank. My 99 has one there. But the system that it is set up to run them as one tank is crazy. Both tanks act as one on the guage. It kinda averages them. The back tank pumps to the front tank when it sences that it needs to to keep them even. The front tank sends it to the engine. Who in the heck could even guess where to start and the cost of adding that would be alot. If I did get a tank that goes in that spot, I think I found one on a web site, how would I do it. The tank I'm sure is for replacing a bad one that is allready there. So all that stuff for a duel tank system is there. Any Ideas would be great.
