This listing features a high-grade Plunger Element, specifically identified by part number 094150-0310. Engineered as a core internal component for the HP0 Fuel Injection Pump, this unit is responsible for generating the extreme hydraulic pressures required in heavy-duty common rail systems. It ensures precise fuel volume displacement during each camshaft stroke, restoring factory-level rail pressure parameters and eliminating internal fuel bypass.
The 094150-0310 is precision-machined exclusively for the Isuzu 6WG1, a robust 14.2-liter inline-six diesel engine widely utilized in the Isuzu Giga commercial truck series and heavy industrial equipment. Because this large-displacement engine relies on sustained high-pressure atomization to maintain its heavy payload torque, the metallurgical integrity of the pumping element is paramount. Constructed from hardened steel alloys, it resists the severe abrasive wear caused by microscopic particulates and low-lubricity commercial diesel.
Failing pump internals often manifest as severe engine surging, hard starting, or low rail pressure fault codes under load. Overhauling the injection assembly with a brand-new 0941500310 restores the exact micron-level clearance between the plunger and barrel. This direct replacement ensures your Isuzu 6WF1/6WG1 achieves optimal thermal efficiency, reliable cold-weather starts, and compliance with stringent heavy-duty emission standards.
