Fuel Line MAN 51123045849

For fleets operating MAN TGA, TGS, and TGX series trucks, the Fuel Line (OE No. 51123045849) is one of the components requiring periodic inspection in the engine fuel system. When the vehicle experiences fuel leakage, insufficient fuel delivery, reduced engine power, or starting difficulties, this line is often a key item for troubleshooting. The line operates long-term in high-temperature and vibration environments within the engine compartment, where material may harden, crack, or lose sealing integrity at connections due to aging, causing fuel leakage and subsequently affecting engine fuel supply stability and driving safety. The product is manufactured from fuel-resistant material with a net weight of approximately 48g, with mounting dimensions strictly following original standards for direct replacement. Fitting MAN TGA, TGS, TGX series trucks (Euro 6, D2066/D2676 engines), the aftermarket offers new, remanufactured, and second-hand options, serving as a routine spare part for fleet preventive maintenance and breakdown repair.
