At 4 State Trucks, we have a great selection of Peterbilt 367 Diesel Fuel Tanks. Whether you need a front-fill auxiliary tank for extra range, a rear-fill tank with up to 135-gallon capacity, or a center-fill option like the 100-gallon aluminum tank for better balance, we’ve got options for you. We also offer rectangular hydraulic tanks with mounting kits, sturdy side-mount reservoirs, and smaller DEF tanks to support your emissions system. Built for durability and performance, these tanks come in a variety of sizes to keep your rig running strong.
