Zexel Delivery Valve 39A | 131160-5320 | Isuzu Mitsubishi

New Zexel delivery valve (part number 131160-5320, type 39A) for Zexel/Bosch inline diesel injection pumps used on Isuzu and Mitsubishi engines. The delivery valve seats at the top of each pumping element; it delivers pressurized fuel to the injector line, then closes and retracts to sharply end injection and hold residual line pressure. It replaces Bosch 9413610308 and Isuzu 1156410310.

Key Features:

• Zexel delivery valve, part number 131160-5320 (type 39A)
• Controls fuel delivery and end-of-injection for one pumping element
