When it comes to installing the tank, it's a matter of drilling six holes and bolting it to the frame. After that, you make a new fuel line and you're good to go. Also, No Limit has tanks for a variety of years and makes of trucks, and if they don't have an off-the-shelf unit, they can build you a custom one-off with the provided dimensions.
For this install, we headed down to the Primedia Tech Center, where Project Get Shorty sat ready for battle. It took my brother Chance and I nearly four hours to complete the install, which was partly due to the fact that there was no bed on the truck. However, one cool thing about the No Limit tank is that it can be installed with the bed on the truck since the tank mounts on the bed's underside, and No Limit gives you the appropriate hardware.

Normally, for this install you need to remove a few crossmembers toward the rear of the frame, but because Shorty has already had the factory crossmembers removed, we got straight to business. The tank mounts on the frame's underside between the framerails. Using a floor jack, Chance placed the tank in the mounting position.

We decided we would place the tank 2 1/2 inches from the rear of the frame; therefore, we made our measurement and placed the tank accordingly.

Making sure the tank was squared up, we took one more set of measurements, but this time we measured from the rear of the frame to the forward edge of the tank.

With the tank squared up, we placed the No Limit steel mounting strips on the underside of the tank flanges and marked where the mounting holes needed to be drilled.
