Tank Parts & Mounting
AlumiTank builds direct-fit Peterbilt fuel tanks engineered to meet or exceed OEM specifications. Each tank is precision-fabricated from 5052-H32 aluminum, TIG-welded for strength, and pressure-tested for leak-free performance. Whether you need a replacement tank for a Peterbilt 379, 389, or 579, or a custom configuration to match your setup, AlumiTank delivers perfect fitment, fast turnaround, and long-lasting quality — all made in the USA.
Custom Fabrication
When standard tanks don’t fit your needs, we’ll build one that does. From non-standard lengths to dual-compartment combo tanks, our engineers can match any spec. We work directly with truck owners, equipment manufacturers, and service body builders to deliver tanks that fit the first time — and perform for years.
