This product uses part number 740035 with OE number reference 03-37017-000. It is compatible with selected Freightliner truck fuel tank applications when the cap size, mounting style, and OE number match. Fitment should be confirmed before ordering.
Material and Structure
The cap features a silver metal body, black sealing area, attached chain, and retaining pin. This structure is designed for replacement service where the fuel tank cap must seal properly and remain secured to the vehicle.
