Peterbilt 587 Fuel Tanks

Frequently Asked Questions About Peterbilt 587 Fuel Tanks

What size fuel tanks are available for the Peterbilt 587, and which configuration should I choose?

Peterbilt 587 fuel tanks typically range from 100 to 150 gallons per tank, with dual tank setups offering 200-300 gallon total capacity. The most common configurations are 120-gallon aluminum tanks for weight savings or 150-gallon tanks for maximum range. Your choice depends on your typical routes - long-haul drivers often prefer dual 150-gallon setups, while regional drivers may opt for single tank or dual 120-gallon configurations to reduce weight and improve payload capacity.

Will these fuel tanks fit my specific year Peterbilt 587, and what about mounting hardware?

Our Peterbilt 587 fuel tanks are designed to fit model years 2011-2017. Most installations use the existing mounting points, but trucks with aftermarket modifications may require additional hardware or bracket adjustments.

What's the difference between aluminum and steel fuel tanks for my 587?

Aluminum tanks weigh approximately 50% less than steel equivalents, saving 100-150 pounds per tank, which directly increases payload capacity. They resist corrosion better, especially important in winter states using road salt. Steel tanks cost 20-30% less upfront and offer superior impact resistance, making them ideal for construction or off-road applications. Both materials meet DOT standards, but aluminum tanks typically last 15-20 years versus 10-15 years for steel with proper maintenance.

How difficult is the installation process, and what tools are required?

Installation typically takes 3-4 hours per tank for experienced mechanics. You'll need basic hand tools, a floor jack or transmission jack to support the tank during installation, and potentially a reciprocating saw if removing old brackets. The challenging part is disconnecting fuel lines without spillage, properly torquing mounting straps to 65-75 ft-lbs, and ensuring proper clearance from exhaust components. Many drivers choose professional installation due to fuel system safety concerns and the need to properly bleed air from the system.

Tanks feature standard NPT ports for fuel gauges, vents, and return lines. If you're running a dual tank setup with crossover lines, ensure you order tanks with matching port configurations - typically a 1-inch transfer port located 6 inches from the tank bottom.
