0103 064 VOLVO and RENAULT TRUCKS Overflow Valve

This precision-engineered component serves a critical role within the fuel system, specifically functioning as an overflow valve for the injector pump. Designed to maintain optimal pressure regulation, it is manufactured with heavy-duty grade materials to withstand the rigorous demands of heavy commercial vehicle operation. This ensures consistent performance and protects the engine from pressure fluctuations.

0103 064 is the OE-equivalent of the VOLVO 21697342 and RENAULT TRUCKS 7421697342 components used in various heavy-duty truck systems. It is fully compatible with several high-standard references including VOLVO 20523255, 20741620, 21010372, 21419969, and RENAULT TRUCKS 7420741620, 7421010372, 7421697342. This ensures seamless integration into existing fuel delivery architectures.

For workshop technicians performing maintenance or engine repairs, this part offers a direct fitment due to its M10x1 thread specification. Regular inspection of the injector pump assembly and checking for any signs of pressure loss or leakage around the valve connection is recommended during standard service intervals to maintain peak vehicle efficiency.
