Frequently Asked Questions About Ford F650-F750 Truck Fuel Tank Accessories

What size fuel tanks are available for my Ford F650 or F750, and how do I determine which capacity I need?

Ford F650-F750 trucks typically accommodate fuel tanks ranging from 50 to 150 gallons, with the most common sizes being 50, 65, 100, and 150-gallon options. To determine the right capacity, consider your typical route distances, payload weight, and fuel efficiency. For local delivery trucks, a 50-65 gallon tank often suffices, while long-haul or heavy-duty applications benefit from 100-150 gallon tanks. Check your truck's frame rails for mounting space - dual tank setups are popular for extended range without compromising ground clearance.

Are aftermarket fuel tanks compatible with my specific F650/F750 model year, and what should I watch for?

Most aftermarket fuel tanks fit F650/F750 models from 2000-present, but mounting brackets and fuel system connections vary between generations. Pre-2016 models use different emission control systems than 2016+ trucks, affecting tank vent requirements. Always verify the tank includes the correct fuel pump module opening (5-bolt or 6-bolt pattern) for your year. Trucks with hydraulic systems may have different frame rail spacing, so measure your available mounting area before ordering.

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

You'll find three main options: aluminum, aluminized steel, and polyethylene. Aluminum tanks offer the best weight savings and corrosion resistance but cost more. Aluminized steel provides good durability at a moderate price point and works well in most climates. Poly tanks resist corrosion and denting but may not be suitable for all mounting configurations or extreme temperatures. For trucks operating in salt-heavy regions or carrying corrosive materials, aluminum is worth the investment.

Can I install a replacement fuel tank myself, or do I need professional installation?

While mechanically inclined owners can handle basic tank swaps, several factors make professional installation advisable. You'll need to safely drain and dispose of existing fuel, disconnect electrical connections for the fuel pump and sending unit, and potentially modify fuel lines. Proper grounding is critical to prevent static discharge. Most installations require 4-6 hours and specialized lifting equipment. If your truck has auxiliary equipment or custom modifications, professional installation ensures compatibility and safety compliance.

What additional accessories do I need when replacing my fuel tank?

Plan to replace the fuel tank straps, mounting hardware, and rubber isolators during installation - these wear items are inexpensive but critical for secure mounting. New fuel lines and connections are recommended if yours show any wear or corrosion. Consider adding a fuel tank sump if you operate in cold climates to prevent fuel gelling. Don't forget a new locking fuel cap and anti-siphon device for security. Budget an extra $150-300 for these supporting components to ensure a complete, reliable installation.
