Ford F600-F700 Truck Fuel Tanks

Frequently Asked Questions About Ford F600-F700 Truck Fuel Tanks

What size fuel tank do I need for my Ford F600 or F700, and will it fit my specific year model?

Ford F600 and F700 trucks typically use 50-gallon or 60-gallon fuel tanks, though some models can accommodate up to 80-gallon tanks. Compatibility varies by year: 1980-1998 models generally share the same mounting brackets and dimensions, while 1999-2003 models may have different strap configurations. Always verify your truck's specific year and check the tank's mounting strap spacing (typically 26" or 30" center-to-center) before ordering. Most tanks are designed as direct replacements for OEM specifications.

Are these fuel tanks made of steel or aluminum, and which material is better for my truck?

Both steel and aluminum fuel tanks are available for F600-F700 trucks. Steel tanks are more affordable and highly durable but can rust over time, especially in areas with road salt. They typically feature aluminized coating for corrosion resistance. Aluminum tanks cost 20-30% more but offer superior corrosion resistance and are about 40% lighter, improving fuel economy. For trucks operating in coastal areas or regions with heavy road salt use, aluminum is the better long-term investment.

Can I install a replacement fuel tank myself, or do I need special tools?

Installation typically takes 2-4 hours and requires basic hand tools including socket sets, jack stands, and a floor jack to support the tank during installation. You'll need to drain the existing tank completely and may need a helper to position the new tank. Critical steps include properly torquing the mounting straps (typically 25-30 ft-lbs) and ensuring all fuel line connections are secure. While DIY installation is possible, professional installation is recommended if you're uncomfortable working with fuel systems or lack proper ventilation.

What's the difference between round and rectangular fuel tanks for these trucks?

Round tanks (typically 19" or 23" diameter) are the most common OEM style for F600-F700 trucks and offer better structural integrity and easier mounting. Rectangular or D-shaped tanks provide increased capacity in the same frame space and are popular for vocational trucks needing extended range. Round tanks use strap-style mounting, while some rectangular tanks may require bracket modifications. Ensure your choice matches your frame rail spacing and doesn't interfere with exhaust or driveshaft components.

Do these replacement tanks come with sending units, straps, and other necessary hardware?

Most replacement fuel tanks are sold as tank-only units without sending units, straps, or fittings. You'll typically need to transfer your existing sending unit (fuel gauge sensor) or purchase a new one separately. Mounting straps are usually sold separately for $40-60 per set. Some suppliers offer complete kits including tanks, straps, and sending units for $50-100 more than tank-only options. Always verify what's included before ordering to avoid installation delays.
