Peterbilt 587 Fuel Tank Acc.

Frequently Asked Questions About Peterbilt 587 Fuel Tank Acc.

What types of fuel tank accessories are available for the Peterbilt 587?

This category covers components that mount to or work alongside the fuel tanks on a Peterbilt 587, including fuel tank straps and strap kits, mounting brackets, fuel tank caps, sending unit and gauge hardware, drain plugs, fuel crossover tubes and fittings, tank supports, and related hardware such as bolts, clamps, and gaskets. These parts are meant to support, seal, or maintain the fuel tanks rather than replace the tank itself.

How do I know if a fuel tank accessory will fit my specific Peterbilt 587?

Fit depends on your truck's tank size, mounting configuration, and build date, since Peterbilt may have used different tank diameters or strap styles across production runs. Before ordering, check your tank's diameter, the distance between mounting points, and the style of your current strap or bracket. If you're unsure, having your VIN or an OEM part number on hand will help you or our team confirm compatibility.

Are these accessories made from materials that resist rust and corrosion?

Most fuel tank straps, brackets, and hardware in this category are made from steel or aluminum, often with a protective coating, plating, or finish to help resist corrosion from road salt, moisture, and fuel exposure. Aluminum components naturally resist rust, while steel parts typically rely on coatings like zinc plating or powder coat. Check each product's listing for the specific material and finish before purchasing.

Can I install fuel tank straps and accessories myself, or do I need a professional?

Many customers replace fuel tank straps, caps, and drain plugs themselves with basic hand tools, as these are generally straightforward bolt-on components. However, because a failed strap or bracket can allow a loaded fuel tank to shift or drop, make sure the tank is properly supported before removing old hardware, and torque all fasteners to the correct specification. If you're replacing crossover tubes, sending units, or anything involving fuel lines, use caution and consider professional installation to avoid leaks or spills.

Will replacing fuel tank hardware affect my truck's DOT inspection or compliance?

Fuel tanks and their mounting hardware are checked during DOT inspections, so damaged, cracked, or missing straps, caps, and brackets can result in a violation. Using properly rated replacement parts that match your tank's size and weight capacity helps keep your truck compliant. If you're replacing a fuel cap, make sure it seals correctly and is rated for diesel fuel to avoid evaporation or leak issues during inspection.
