ISUZU Fuel System Overflow Bolt M8x18mm - ISUZU
Fuel system overflow (hollow) bolt dedicated to a wide range of ISUZU power units. This component is responsible for the proper return of excess fuel from the injection pump or injectors back to the tank. Precision-engineered flow channels ensure pressure stabilization in the low-pressure system, which is essential for smooth engine operation and protecting the injection system from air pockets.

Technical Advice: Overflow bolts are precision components and relatively fragile due to their hollow structure. During installation, it is mandatory to use new sealing washers (copper or aluminum) to avoid leaks and "false air" (air intake) in the system. Care should also be taken when tightening – exceeding the recommended torque can lead to shearing the bolt. Before installation, check the patency of the internal channels to ensure free fuel return.
