J&J knows that a go-kart not on the track is a go-kart not generating profits. That's why we designed extra capacity fuel tanks to keep your go-karts on the track all day long. These rugged "cross-linked" polypropylene fuel tanks handle Ethanol fuels without problem. Depending on the kart selected, the extra capacity fuel tanks come in 2.2 gallon (8.33ltr), 3.3 gal (12.49ltr), 4.75gal (17.98ltr) single tanks and the 4.4gal (16.65ltr) dual side tank system. Be safer and keep revenues going; ask which system will run your karts all day and avoid the mid-afternoon fill up.
