Fast forward to 4 years later it was time to reinstall, buy new, or stick a tank under the bed. I chose to reuse. Mainly because of the horror stories i had heard about aftermarket in cab tanks. I also didn't feel like the extra work of sticking it under the bed and figuring out where the filler neck was going to be.

My original was in good shape with no rust in it. Even after sitting in a shed with fuel in it for 4 years it had no rust in it. So I flushed it the best i could, and added a new "filter sock" on the end of the pickup tube, and reintsalled it in the cab. Even resealed nicely in the old original filler neck grommet. Working flawlessly to this day.

So unless you visually inspected the tank and it has either rusted or it has some sort of weird leaking issue. I'd simply reuse the original.
