International ProStar Fuel Tanks

Frequently Asked Questions About International ProStar Fuel Tanks

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

International ProStar fuel tanks typically come in 70, 100, 120, and 150-gallon capacities. These tanks are designed to fit ProStar models from 2008 through 2017. The 26-inch diameter tanks are standard for most ProStar configurations, while some models may require 23-inch diameter tanks. Always verify your truck's OEM and original tank specifications before ordering, as tank compatibility can vary based on wheelbase, cab configuration, and factory options.

Are aftermarket fuel tanks made from aluminum or steel, and which material is better for my application?

Most aftermarket ProStar fuel tanks are available in both aluminum and steel options. Aluminum tanks are lighter (reducing overall vehicle weight by 50-70 pounds compared to steel), resist corrosion better, and are ideal for drivers concerned about fuel economy. Steel tanks are typically 20-30% less expensive, offer better impact resistance, and are easier to repair if damaged. For trucks operating in northern climates with heavy road salt exposure, aluminum is generally recommended despite the higher initial cost.

What are the most common installation challenges when replacing ProStar fuel tanks?

The primary installation challenges include aligning new tank straps with existing mounting points, especially on trucks with aftermarket suspensions or modified frames. Many installers report needing to modify or replace fuel tank brackets when switching between different capacity tanks. Additionally, fuel sending unit compatibility can be an issue - some aftermarket tanks require transferring your original sending unit or purchasing a compatible replacement. Plan for 3-4 hours of installation time and ensure you have proper lifting equipment, as these tanks can weigh 80-150 pounds empty.

Do aftermarket fuel tanks come with all necessary mounting hardware and fuel fittings?

Most quality aftermarket fuel tanks include basic mounting straps and hardware, but rarely include all necessary components. You'll typically need to purchase separately: fuel cap, sending unit (if not transferring from old tank), fuel pickup tube, vent fittings, and crossover line fittings for dual tank setups. Some manufacturers offer complete kit options that include these components, which can save time and ensure compatibility. Always verify what's included before ordering to avoid installation delays.

What's the difference between polished, brushed, and painted finish options for aluminum tanks?

Polished aluminum tanks feature a mirror-like finish that looks impressive but requires regular maintenance with aluminum polish to prevent oxidation and maintain appearance. Brushed aluminum provides a satin finish that hides minor scratches better and requires less maintenance while still looking professional. Painted tanks (usually powder-coated black or white) offer the best corrosion protection and lowest maintenance but may chip over time from road debris. For trucks that see heavy use or limited washing, brushed aluminum offers the best balance of appearance and practicality.
