Adding your products to cart

Keep your rig fueled and road-ready with our lineup of high-quality aftermarket diesel fuel tanks for the Peterbilt 389. Whether you're replacing a worn-out tank or upgrading to more capacity, we've got aluminum fuel tanks built to handle the miles.

Why Upgrade Your Pete 389 Aluminum Fuel Tank?

- Tough, Lightweight Construction: Aluminum resists corrosion and weighs less than steel—great for fuel efficiency and durability. - Built for the Road: These tanks are designed to handle vibration, heat, and the rough conditions of daily hauling. - Multiple Configurations: Choose from rear, front, or center-fill designs to match your truck’s plumbing and refueling needs. - More Fuel = Fewer Stops: Go longer between fuel-ups with larger capacity options—ideal for long hauls. - Ready to Install: Available with driver-side or passenger-side mounting. Just remember—you’ll need longer fuel hose connectors and larger tank straps or brackets when upgrading to a bigger tank. These tanks are available in rear-fill, front-fill, and center-fill designs, so you can choose what fits your current setup—or build the custom configuration that works best for your route. With capacities ranging from 80 gallons to 150 gallons and 23-inch or 26-inch diameters, there’s a tank here that fits your truck and your fuel range needs. Consider a full fuel tank storage upgrade: - Hydraulic Reservoir Tanks for combo fuel and hydraulic needs - Auxiliary Fuel Tanks for extra storage or specialized applications (not always in stock) - Tank Accessories including anti-theft fuel caps and secure fuel tank brackets and straps Whether you're replacing a damaged aluminum tank or you’re upgrading sizes for better fuel range, our aftermarket Peterbilt 389 fuel tanks deliver the performance, reliability, and fit you need.

Frequently Asked Questions About Peterbilt 389 Diesel Fuel Tanks

Will a replacement fuel tank fit my Peterbilt 389 without modifications?

Fuel tanks for the Peterbilt 389 are typically available in various diameters, lengths, and gallon capacities to match factory configurations. Because tank mounting points, strap spacing, and frame rail width can vary depending on your truck's specific build, it's important to confirm the diameter, length, and mounting style of your original tank before ordering. Checking these measurements against the product listing will help ensure a proper fit.

What materials are these fuel tanks made from, and how do they hold up over time?

Peterbilt 389 fuel tanks are commonly offered in aluminum, though steel options may also be available depending on the manufacturer. Aluminum tanks are popular for being lightweight and naturally resistant to corrosion, which can help extend service life in a variety of weather and road conditions. The gauge and construction quality can vary between brands, so reviewing the manufacturer's specifications is a good way to gauge durability expectations.

Do these tanks come with the necessary mounting hardware, straps, and fittings?

This varies by product and manufacturer. Some fuel tanks are sold as a complete kit with straps, mounting brackets, and fittings included, while others are sold as the tank only, requiring you to reuse existing hardware or purchase components separately. Always check the product description or contact our team to confirm exactly what's included before you buy.

Can I install a diesel fuel tank myself, or should I have a professional do it?

Fuel tank installation involves handling fuel lines, venting, and securing a heavy component to the frame rail, so many owner-operators choose to have this done by a qualified technician or diesel shop. If you have experience with heavy-duty truck maintenance and the proper tools, installation is possible in a home shop setting, but improper installation can lead to leaks or fitment issues, so proceed carefully or seek professional help if you're unsure.

How do I choose the right fuel capacity and shape for my truck?

Fuel tank capacity and shape often depend on your truck's chassis configuration, intended use, and how much fuel range you need between fill-ups. Common shapes include round and D-shaped tanks, and capacities can range widely. Consider your typical routes, fuel stop availability, and any weight or clearance restrictions before selecting a tank, and compare these factors against your current setup to find the closest match or an upgrade that suits your needs.
