Fuel and Lube Bodies

Genuine Mega Design for Fuel and Lube Bodies (MFL)

Mega's complete line of fuel and lube bodies for rigid and articulated trucks are designed for stable operation, proper weight distribution and long life. Mega service bodies feature an integrated power system which uses fuel supplied directly from the platform fuel tank. The body is fully functional with the truck turned off, saving service meter hours, emissions and fuel consumption. The power system allows complete testing in the factory prior to field installation, minimizing labor cost and chassis integration issues. Every service body includes a complete set of technical manuals detailing installation, operation, maintenance, inspection and replacement parts. Mega bodies are constructed with premium materials and are inspected throughout the manufacturing process to ensure reliability.

Mega fuel and lube bodies can be purchased for integration with a dealer-provided truck or as a complete solution with a Mega-provided truck. Purchasing your complete solution directly from Mega streamlines the ordering process and significantly reduces the complexities related to delivery timing and shipping.

The general specifications below reflect nominal capacities for Mega standard configurations. Please contact our Mega Sales Team regarding shipping information and models not listed.
