Revamp your setup with the 110?gallon BESTfit Aluminum Fuel Tank (24.5??54?inch), a heavy?duty replacement designed to fit Kenworth T800 and W900 series trucks, including curved glass and AeroCab models from the mid?1980s through 2007. Made from 11?gauge aluminum with welded seams and CNC laser?cut precision, this cylindrical DOT?compliant fuel tank holds up to 110?gallons of diesel and is available in rear?fill driver or passenger?side configurations, with sending unit manifold options depending on your choice. It's built to replace OEM tank K444?0486N0102J110, sold individually, and backed by a warranty against defects in materials and workmanship from the date of purchase. Caps and fittings are not included, so those are purchased separately, and confirming manifold style, filler location, and fitment details before ordering helps ensure compatibility with your truck.
