Features
- 12 Gauge Steel Plate: ATB builds the S-TS5 from 12 gauge steel plate, fully seam welded, and calls it a contractor grade tank.
- 102 Gallon Capacity: The 20" x 24" x 54" tank holds 102 gallons, as ATB lists it.
- Weld-On Fittings: Machined weld-on fittings: two 2" for pump and filler cap, one 1-1/2" for a gauge and one 3/8" for a roll-over valve on top, plus a 3/8" bottom side drain.
- Internal Baffles: Built-in baffles reduce sloshing and keep the fuel stable.
- Brackets And Lift Hooks: Heavy duty mounting brackets and lift hooks are built on, and the tank is reinforced for mounting.
- Black Powder Coat: A zinc epoxy primer and baked black powder topcoat resist corrosion, and ATB pressure tests each tank for leaks.
Description & Fitment
The ATB S-TS5 is a 102-gallon auxiliary fuel tank built from 12 gauge steel plate and fully seam welded. It measures 20" high, 24" deep and 54" wide, with internal baffles, machined weld-on fittings for pump, filler, gauge and roll-over valve, and a 3/8" bottom side drain. ATB pressure tests it for leaks and finishes it in black powder coat over a zinc epoxy primer. It is for diesel fuel only.
Fitment & Compatibility
How to choose: check that your bed or deck fits the 20" x 24" x 54" footprint and can carry a full 102-gallon tank plus its 274 lb empty weight.
ATB requires a spring loaded mounting kit and mounting to its guidelines; improper mounting voids the warranty.
Fits: Pickup beds, flatbeds and service decks with a 54" x 24" footprint

Frequently Asked Questions
Will it fit my truck?
Measure the space for a 54" wide, 24" deep, 20" high tank and make sure the truck can carry the full load. Contact us if you are unsure which mounting kit to pair with it.
What fuel can I use?
Diesel only, with a vented filler cap, as ATB specifies for its TS tanks.
How do I measure for it?
The tank is 20" high, 24" deep and 54" wide. Check your bed or deck for that footprint and leave room to reach the filler, pump and gauge fittings on top.
Do I have to mount it a certain way?
Yes. ATB says the tank must be mounted to its mounting guidelines with a spring loaded mounting kit; improper mounting voids the warranty.
Is it leak tested?
ATB pressure tests its tanks for leaks.
How do I care for the finish?
Wash with mild soap and water and touch up chips with paint so the steel does not rust.
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.
