Why Upgrade Your Freightliner’s Fuel Tank System?

Replacing a damaged tank or upgrading a worn-out part helps: - Prevent leaks and fuel loss - Improve fuel system efficiency and safety - Reduce downtime and boost range - Keep your Freightliner looking sharp and running smooth
It's also the best time to start replacing components on your Freightliner suspension frame - since this is where your tank sits. Your Freightliner exhaust parts are adjacent to your tank, so consider upgrading these in one fell swoop. Lastly, your tank sends fuel to the engine. So any damaged or worn-out fuel tank coolant lines should get replaced while you're at it. With that said, whether you’re doing a total tank swap or just replacing a pickup line, this category is your one-stop shop.
