Answer: For CAT 320B and 320C excavators, we recommend replacing the 1174089 every 500 hours or immediately if you notice loss of engine power, rough idling, or if the "water in fuel" dashboard light illuminates. Regular replacement prevents high-pressure common rail damage.
Answer: This is often caused by air in the fuel lines. Use the fuel priming pump to bleed air from the system. Ensure the 117-4089 gasket is lubricated with clean oil before installation to prevent vacuum leaks.
Answer: Our 117-4089 features an OEM-standard tri-metal structure. It is trusted by repair shops and equipment fleets for its ability to withstand harsh construction environments and protect expensive fuel injectors.
