Extend your driving range and eliminate frequent fuel stops when towing long distances with your 2001–2004 Chevy Silverado or GMC Sierra 2500HD/3500HD with our selection of LB7 Duramax fuel tanks and accessories. The modest capacity of the factory underbody tank often limits long-haul travel, especially when pulling heavy fifth-wheels or commercial trailers under demanding conditions. Upgrading to a direct-fit, high-capacity cross-linked polyethylene replacement fuel tank increases usable capacity up to 50+ gallons without sacrificing valuable bed space or ground clearance. We supply heavy-duty replacement fuel tanks, fuel level sending units, straps, and fuel tank sump kits from industry leaders like Titan Fuel Tanks and S&B Filters. Browse our 6.6L LB7 fuel tanks and transfer accessories below to keep you on the road longer between pumps.
