PT27 Diesel Plunger Barrel For Bo-sch VE Fuel Injection Pump
PT27 is a robust high-pressure plunger barrel for Bo-sch VE4 mechanical pumps and Isuzu 4BC2 3.9L diesel engines. Made of wear-resistant alloy steel with precision grinding and surface treatment, it withstands 1200bar continuous pressure and 190–210bar opening pressure, meeting Bo-sch quality standards. It perfectly matches injectors 105118-1870/0432131643 and nozzles DN0SD187/DLLA140P643. Delivers consistent fuel delivery and stable pressure output, resolving hard cold starting, idle roughness, power drop, and high fuel consumption in light trucks and generators. 100% factory tested for pressure, leakage, and fuel delivery; it is a cost-effective replacement for VE pump maintenance.
