Frequently Asked Questions About Freightliner Cabover Diesel Fuel Tanks

Will this fuel tank fit my specific Freightliner cabover model?

Freightliner cabover models such as the FLA, FLB, and FLC were built over many years with different frame widths, mounting configurations, and tank capacities. Always confirm your truck's model year and chassis specs against the listed fitment details before ordering, and reach out to our parts team if you are unsure -- they can help verify fitment using your VIN or existing tank measurements.

What material are these diesel fuel tanks made from, and does it affect performance?

Fuel tanks in this category are typically constructed from aluminum or steel. Aluminum tanks are lighter and naturally corrosion resistant, which can help with long-term durability and fuel economy, while steel tanks tend to be more rugged for heavy-duty applications. The right choice depends on your priorities around weight savings versus overall toughness.

How do I properly measure for a replacement tank?

Before purchasing, measure the diameter, length, and mounting strap spacing of your current tank, and note the location and size of fuel line, sending unit, and vent fitting openings. Comparing these measurements to the product specifications listed on each tank's page will help ensure a proper fit and reduce the chance of needing modifications during installation.

What is involved in installing a replacement diesel fuel tank?

Installation generally involves draining and disconnecting the old tank, removing the mounting straps or brackets, and transferring or replacing components like the sending unit, fuel lines, and vent tube to the new tank. Most installations can be handled by a shop with basic hand tools, but because these tanks hold diesel fuel, proper safety precautions and a secure mounting job are essential.

Do these tanks come with the sending unit, straps, and fittings included?

This varies by product listing -- some tanks are sold bare while others include mounting straps or fitting bungs. Check the specific product description for what is included, and if a sending unit or strap kit is not included, we carry those components separately so you can complete the installation with matching parts.
