Features
- L-Shape Tank and Chest: ATB combines an aluminum toolbox chest with an L-shape auxiliary fuel tank, so fuel and tools ride on one unit.
- 64 or 95 Gallons: The 16" tall version holds 64 gallons and the 24" tall version 95; ATB rates it for diesel, water, oil and biofuels, not gasoline.
- Top and Side Ports: Two 2" top connections for filler and pump, a 1-1/2" for a gauge and a 3/8" for a roll-over vent, plus a 3/8" side drain.
- Gas Spring Lid: The top-open single lid stays open hands-free on gas springs.
- Lift Handle Locks: Lift handle locks keep the lid secure against road vibration and unauthorized access.
- Mounting Brackets: Side and front brackets come with it for a truck bed or flatbed; ATB says to use a spring loaded mounting kit.

Installation
- Ratchet wrench
- Wrench
- Drill
- Drill bit
- Tape measure
Here's the short version. Follow ATB's install sheet (below) for your truck's exact positions and hardware.
- Check all parts against the parts list and look over the bed to plan where the tank will mount.
- Set the tank in place to confirm the fit; if it has a toolbox, make sure the lid can open.
- Square the tank, mark the four holes on the truck bed and check no wiring or hoses run under the marks.
- Move the tank aside and drill the four holes (hole size depends on the M3702-TMK or M3705-TMK kit), then clean out the debris.
- Cut the 2" neoprene to tank depth and lay it on the bed ridges at four places.
- Set the tank back, fit the bolts, washers, bushings, springs and nuts and tighten firmly so the tank can still shift if the bed twists.
