Ford LTA / LTL 9000 Truck Fuel Tanks

Frequently Asked Questions About Ford LTA / LTL 9000 Truck Fuel Tanks

What size fuel tanks are available for my Ford LTA/LTL 9000, and how do I determine the right capacity?

Ford LTA/LTL 9000 fuel tanks typically range from 50 to 150 gallons, with 100-gallon and 120-gallon options being the most common. To determine the right capacity, measure your existing tank's dimensions (length x height x depth) and check your frame rail spacing. Consider your typical route distances and whether you run single or dual tank setups. Most long-haul operators prefer 120-150 gallon tanks for extended range, while regional drivers often find 75-100 gallon tanks sufficient.

Will these fuel tanks fit my specific year Ford LTA/LTL 9000?

Our fuel tanks are designed to fit Ford LTA/LTL 9000 models from 1978 through 1998. However, there are important variations: 1978-1987 models typically use 23-inch diameter tanks, while 1988-1998 models commonly use 25-inch diameter tanks. The mounting strap configurations also differ between early and late models. Always verify your truck's specific year and check the existing tank diameter before ordering. Tanks are typically side-specific, so ensure you're ordering for the correct driver or passenger side.

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

We offer both aluminum and steel fuel tanks. Aluminum tanks (typically 0.125-inch thick) weigh about 50% less than steel, resist corrosion better, and are ideal for weight-conscious operations. Steel tanks (14-gauge) are more impact-resistant and generally cost 20-30% less than aluminum. For trucks operating in harsh winter conditions with heavy road salt exposure, aluminum is strongly recommended. Steel tanks work well for local operations where weight isn't critical and initial cost is a primary concern.

What installation hardware and steps are required to mount these fuel tanks?

Installation requires tank straps (usually 2-3 per tank), mounting brackets, rubber isolators, and grade 8 bolts. The process typically takes 2-4 hours per tank. Key steps include: draining the old tank completely, disconnecting fuel lines and sender wiring, removing old mounting hardware, positioning the new tank with proper clearance (minimum 1 inch from frame rails), and ensuring all connections are secure. Many customers report needing new fuel line fittings due to thread differences between old and new tanks. Professional installation is recommended if you're not comfortable working with fuel systems.

Do these tanks include sending units, and are they compatible with my existing gauge?

Most replacement tanks come without sending units, which must be purchased separately. Ford LTA/LTL 9000 trucks typically use either Stewart Warner or Rochester sending units with specific ohm ranges (usually 33-240 ohms). Before ordering, check your existing sending unit's brand and ohm rating to ensure gauge compatibility. Universal sending units are available but may require gauge recalibration. The sending unit mounting hole is typically a standard 5-hole SAE pattern, but verify this matches your current setup to avoid modification.
