So i plan on putting in my single stack this weekend. I currently have a aux fuel tank in the bed. It only has the diesel left in it that i couldnt pump out. I am trying to sell the tank, but if i cant, i have use for it down the road.

But my question is, Will the heat from the exhaust be high enough to cause problems with the tank. If the tank heats up too much will the pressure in the tank be too high for whatever kind of safety the tank has built into it?

 

Shouldn't be a problem. The tank should have a vent that will get rid of any excess pressure.

 

Shouldn't be a problem if you have a bit of air space between tank, and stack.
