UNIVERSAL BOSCH ZEXEL DIESEL FUEL FEED AC PUMP CHECK VALVE REPAIR REBUILD KIT (01-01-1500 / 2447-010-004 / 2447010004 / 9441037000)

Overview

The Universal Bosch / Zexel Diesel Fuel Feed AC Pump Check Valve Repair Kit (01-01-1500 / 2447-010-004) is a heavy-duty fuel system overhaul component engineered for mechanical diesel fuel lift / feed pumps (AC Pumps) mounted on inline injection pumps (Bosch, Zexel, Diesel Kiki, Denso FP/K, FP/KS, and FP/KE series). Commonly used across commercial Japanese trucks (Isuzu, Hino, Mitsubishi Fuso, Nissan UD) as well as agricultural, industrial, and European commercial diesel engines, this kit contains the essential spring-loaded one-way suction and delivery check valves, compression springs, and sealing washers. Over time, worn, pitted, or sticking internal valves allow fuel to drain back into the tank, causing morning hard starts, loss of low-pressure fuel supply, engine hesitation under load, and inability to hand-prime. Rebuilding the check valves restores proper line pressure, positive fuel delivery, and instant starting reliability without replacing the complete pump assembly.

Engineered to commercial fleet specifications for dependable workshop replacement, fuel system overhaul, and chassis maintenance.
