About this part
294000-0265 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 294000-0265, 97328886. Application recorded for this part: Fits Isuzu — 4HK1 5.2L NPR.
Every injection event depends on this pump producing pressure at exactly the right moment. Because it also carries its own lubrication, poor supply pressure and fuel dilution do disproportionate damage — which is why the supply side should always be checked alongside the pump itself.
Symptoms associated with pump wear include hard starting when hot, loss of power, unstable idle, excess smoke, timing that will not hold, and in some cases diesel getting into the lubricating oil via a leaking drive shaft seal.
Diagnose the supply side before blaming the pump. Restricted filters, a tired lift pump or air being drawn into the suction line will produce symptoms almost identical to internal pump wear, and are far cheaper to resolve.
Fitment notes: this unit must be timed to the engine, not simply bolted on. Never force the shaft to align — turn the engine over to meet it. Prime the system before cranking, fit a new drive seal where specified, and verify supply pressure from the lift pump before start-up. Running a dry pump, even briefly, causes damage that no warranty will cover.
What we do differently: every core is stripped to components, inspected against wear limits and measured before anything is reused. Worn parts are replaced, not cleaned and refitted. After reassembly the unit is bench-tested — delivery, return flow, opening pressure and leakage — and only units inside specification are dispatched. We can send the test sheet for your order before it leaves. Every remanufactured unit carries a 12-month warranty.
