Im looking at putting a tool box with a aux fuel tank built in into my 98 quadcab longbed. But I'd also like to put stacks on later down the road. My question is how close could I get the box to the stacks? I dont really want to space the box 2 feet away from the stacks to stop potential fire. Anyone know where to get a good box/fuel tank with some heat resistance? Or would diamondplate itself hold up to the heat. I just dont want to put a bunch of $$ and work into it and end up burning the truck to the ground. I also like the idea of putting the stacks through the box, but then again even if I weld a good sleeve through the box to seal the fuel Im still adding a lot of heat. Advice is appriciated!! Thanks!

 

No takers? Im wondering if the tool boxes w/ the tanks built in have a speacial coating.. or if its just bare aluminum. I'd like to put both stacks and a tank...

 

I've been pondering the same thing... Most tanks are either powder coated steel or bare aluminum.I don't like the fact of moving the whole setup back 6 inches to install stacks... Thats valuable bed space wasted. I thought of putting the stacks through a toolbox which is doable but it's alot of fab work to put the stacks through the lids and be able to open them.. The tank still causes a problem without moving the tank back. My only conclusion was to find a little 50 gal. L-tank for a mini truck with a tool chest and offset it to the driver side with a single stack pass side... or center it for dual stacks if there was enough room

 

You wont start a fire just off the heat from the stacks. When you are moving down the road there is decent airflow through that area, and if you want to add a bit more, you can cut the hole slightly bigger in the bottom of the bed and maybe put a little flap of metal or something hanging down to catch some air and run it up through there while driving. It would be cool to run stacks through a toolbox, but it looks like so much work and I dont think I could ever get the toolbox watertight again. I have a single lid box and in order to keep it from hitting the stacks when opened, there is a good 3-4" gap when closed. I wouldnt think it would cause a problem with a toolbox fuel tank.

 

By the time the exhaust gets to the stacks the temperature will have dropped enough to not cause any issues. Add in the dissipated heat into the air, the heat absorbed by the exhaust, etc... and it will be no worse than the sun shining on your tool box.
