International PayStar 5000 Fuel Tanks

Frequently Asked Questions About International PayStar 5000 Fuel Tanks

What size fuel tanks are available for my PayStar 5000, and which models are they compatible with?

We offer fuel tanks ranging from 50 to 150 gallons for PayStar 5000 models from 2012-2024. The most common sizes are 75-gallon and 100-gallon aluminum tanks. Compatibility depends on your specific model year and chassis configuration. PayStar 5000 SFA (Set-Forward Axle) models typically use different mounting brackets than SBA (Set-Back Axle) versions. Always verify your OEM and model specifications before ordering to ensure proper fitment.

Are these fuel tanks made of aluminum or steel, and what's the difference in durability?

Most PayStar 5000 fuel tanks are available in both aluminum and steel options. Aluminum tanks are 40-50% lighter than steel equivalents and resist corrosion better, making them ideal for operations in areas with road salt or coastal environments. Steel tanks are typically 20-30% less expensive and offer excellent impact resistance for severe-duty applications. Both materials meet DOT certification standards, but aluminum tanks generally last 15-20 years versus 10-15 years for steel in typical conditions.

What mounting hardware and straps come with the fuel tank, and what else do I need for installation?

Our fuel tanks include basic mounting brackets and tank straps specific to PayStar 5000 frame rails. However, you'll need to purchase fuel line fittings, sending unit (if not transferring from old tank), and potentially new rubber isolators separately. Some installations require frame rail adapters for 2012-2016 models due to slight dimensional changes. We recommend having new fuel line (5/8" or 3/4" depending on engine), hose clamps, and thread sealant on hand for the installation.

Can I install a larger capacity tank than my original, and will it affect my truck's weight distribution?

Yes, you can typically upgrade to a larger capacity tank, but consider these factors: Moving from a 75-gallon to 125-gallon tank adds approximately 200 pounds when full, which can affect weight distribution on shorter wheelbase models. Larger tanks may require relocating DEF tanks or toolboxes on some configurations. Frame rail spacing must accommodate the wider tank profile - measure at least 26 inches of clearance for 125+ gallon tanks.

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

Installation typically takes 3-4 hours for experienced technicians. You'll need a transmission jack or fuel tank jack to safely position the tank, plus standard hand tools and a torque wrench for proper strap tension (45-55 ft-lbs). The most challenging aspects are disconnecting/reconnecting fuel lines without damage and properly aligning the sending unit. Some 2017+ models have EVAP system connections requiring special disconnect tools. We strongly recommend having a helper for safe tank positioning and using proper jack stands when working underneath the vehicle.
