Ford F650-F750 Truck Fuel Tanks

Frequently Asked Questions About Ford F650-F750 Truck Fuel Tanks

What size fuel tanks are available for Ford F650-F750 trucks, and how do I choose the right capacity?

Ford F650-F750 fuel tanks typically range from 25 to 100 gallons, with 50-gallon tanks being the most common OEM size. When selecting capacity, consider your typical route distances, payload requirements, and mounting space. Larger tanks (75-100 gallons) are ideal for long-haul applications but require proper weight distribution calculations. Always verify your truck's GVWR limits and ensure the added fuel weight won't exceed legal weight restrictions when fully loaded.

Will these fuel tanks fit my specific F650/F750 model year, and what are the mounting differences?

Fuel tank compatibility varies significantly across model years. 1999-2015 models generally share similar mounting configurations, while 2016+ models feature updated frame rails and mounting brackets. Key differences include strap placement (2-strap vs. 3-strap systems), frame rail spacing (34" vs. 37" centers), and fuel pump module compatibility. Always provide your VIN when ordering to ensure proper fitment, as cab configurations (regular, crew, extended) also affect tank placement.

What material options are available, and which is best for my application?

Three main materials are available: aluminized steel (most economical, 5-7 year lifespan), aluminum (lightweight, 10-15 year lifespan, best for weight-sensitive applications), and polyethylene/plastic (corrosion-proof, 15+ year lifespan, impact resistant). Aluminum tanks save approximately 40-60 pounds versus steel but cost 30-40% more. For salt belt regions or chemical hauling applications, polyethylene tanks offer superior corrosion resistance despite being slightly heavier than aluminum.

Can I install a replacement fuel tank myself, and what special tools are required?

Installation typically requires 3-5 hours for experienced mechanics. Essential tools include a transmission jack or fuel tank jack for safe positioning, torque wrench for proper strap tensioning (45-55 ft-lbs typical), fuel line disconnect tools, and proper ventilation equipment. Critical steps include transferring the fuel pump module (if reusing), ensuring proper ground strap connection, and verifying all emissions connections. Professional installation is recommended if you're unfamiliar with fuel system safety procedures or lack proper lifting equipment.

Do aftermarket fuel tanks affect my truck's warranty or emissions compliance?

Quality aftermarket tanks that meet OEM specifications typically don't void warranties, but always verify with your dealer for trucks still under warranty. All replacement tanks must include proper evaporative emission (EVAP) ports and rollover valves to maintain EPA compliance. Look for tanks certified to meet FMVSS 301 (Federal Motor Vehicle Safety Standards) for crash safety. Some states require CARB certification for commercial vehicles - verify your local requirements before purchasing.
