Product description

The fuel return line 7W-2630 is a key component of the injection system that manages the excess fuel not used in the engine cylinders. During operation, the injectors deliver the appropriate amount of fuel to the engine; however, not all the fuel sent to the injectors is utilized. The excess fuel is collected and returned to the fuel tank via the return line, which helps maintain optimal fuel pressure in the injectors. This line is resistant to harsh conditions and the varying temperatures present in the engine compartment. It features connectors and seals that prevent leaks and ensure a secure connection to the injectors and the fuel tank. The return line has a smooth inner surface, which ensures optimal flow, as well as resistance to vibrations and pressure fluctuations, guaranteeing tight connections. It is located in the engine compartment, connecting the fuel injectors to the tank, directing unused fuel back to the tank, which prevents fuel wastage and maintains consistent fuel pressure. The product is used, making it an attractive option for those seeking high-quality parts for construction machinery.

Opinion 5/5

Zakupiony komplet siłowników do Liebherr 564 był w doskonałym stanie, zgodnie z opisem i przesłanymi zdjęciami. Obsługa na wysokim poziomie, bardzo profesjonalna i pomocna – rewelacja. Co więcej, w kontakcie z firmą otrzymałem osobistego opiekuna, który zajmował się sprawą od początku do końca, mogłem również liczyć na bezpłatne doradztwo przy montażu. Szkoda, że w obecnych czasach nie spotyka się zbyt wielu firm z tak profesjonalnym podejściem do klienta. Gorąco polecam.
