The RotopaX 1 Gallon Gasoline pack is a 1-gallon fuel container built from a patented three-layer roto-molded plastic with a barrier resin core that meets EPA and CARB 50-state permeability limits. It measures 13.5" tall by 9.5" wide by just 3" deep, so it lies flat against a bed wall, roof-rack rail, or tire carrier instead of taking up a corner like a round jerry can. Empty it weighs only a couple of pounds; full it carries enough fuel for a meaningful range extension on a remote leg.
The spout and cap assembly are included. A sure-seal gasket keeps it leak-proof whether you mount it flat, vertical, or horizontal, and the spout stays sealed until you press it into the filler neck. The pack mount itself is sold separately in three styles (Standard, DLX, and LOX), and every RotopaX mount fits every RotopaX can size, so a 1-gallon and a larger can share the same hardware and can stack two-high. One maintenance note: crack the cap to vent the can roughly once a day, or after a ~10°F temperature swing or ~1000 ft of elevation change, to relieve pressure.
Backed by a 10-Year Leak Free Guarantee and made in the USA, this is the modular fuel storage that overlanders, Jeep, 4Runner, and UTV owners bolt to the rig and forget about until they need it.
