RotoPax 2 Gallon Diesel Container

The yellow one. RotoPax's only diesel container — color-coded so nobody puts the wrong fuel in your truck at 6am in the dark.

Specifications

This is the only size RotoPax offers in diesel. If you need more range, run two.

Do not switch fluids between containers

The plastic compound is specific to the labelled contents. A diesel pack is not a gasoline pack in a different colour — the materials genuinely differ, and using the wrong fluid compromises the container and voids the warranty. Gasoline is red, diesel is yellow, and that's a regulatory requirement, not a styling choice.

The only roto-molded fuel container CARB will certify

Plenty of fuel cans carry a CARB certificate. RotoPax is the only rotationally moulded one — every other certified container is blow- or injection-moulded, a cheaper process with a thinner wall. RotoPax meets CARB's permeability limit through a patented three-layer process with a formulated barrier material built into the wall.

The white tube in the neck is the Flame Mitigation Device — legally required, prevents flame jetting. Removing it voids the warranty.

Mounting

Beyond RotoPax's Standard, DLX and LOX Pack Mounts, dozens of manufacturers build brackets to the RotoPax pattern — including our Heavy-Duty RotoPax Spare Tire Mount, plus Front Runner, Eezi-Awn, Leitner, Axia Alloys, Xtrusion, TrailRax and RockSlide.

Venting — read this before your first trip

Vent at least once a day, and again for every 10°F of temperature change or every 1,000 ft of elevation gain. Failing to vent will deform the container and voids the fuel-container warranty. Store it completely full or completely empty.
