The fuel feed pump assembly (also known as fuel transfer pump or lift pump) carrying OEM numbers 8-97223289-0 and 8972232890 supplies diesel fuel from the fuel tank to the injection pump on ISUZU 4HF1 4.3L naturally aspirated diesel engines. It is a direct replacement for NKR and NPR series medium‑duty trucks manufactured from the mid‑1980s through the early 1990s.
The 4HF1 is a 4,334 cc inline‑four diesel engine with a bore and stroke of 112 mm × 110 mm, producing up to 88 kW (120 PS) at 3,200 rpm and maximum torque of 285 Nm at 1,800 rpm. Unlike common rail systems, this engine uses an in‑line injection pump that relies on a consistent, low‑pressure fuel supply from the feed pump.
| Part Number: | 8-97223289-0 8972232890 | Product Name: | Fuel Feed Pump Assembly |
|---|---|---|---|
| Car Model: | ISUZU NKR NPR | Engine Model: | ISUZU 4HF1 |
| Condition: | 100% Brand New | Origin: | China Mainland |
| Main Market: | Middle East, Asia, Africa, South America, North America & Europe | ||
| Material: | High-strength aluminum alloy & precision bearings | Quality Standard: | OEM equivalent / ISO quality control |
This ISUZU 4HF1 fuel feed pump 8-97223289-0 directly replaces the factory unit in the following configurations:
| Chassis | Engine | Years | Notes |
|---|---|---|---|
| ISUZU NKR58 | 4HF1 | 1987-1994 | Light‑duty cab‑over |
| ISUZU NKR66 | 4HF1 | 1987-1994 | Updated NKR platform |
| ISUZU NPR58 | 4HF1 | 1987-1994 | Medium‑duty 6‑wheel |
| ISUZU NPR66 | 4HF1 | 1987-1994 | Most common 4HF1 application |
| ISUZU NQR | 4HF1 | 1987-1994 | Medium chassis |
| ISUZU FORWARD F‑series | 4HF1 | 1987-1994 | Export models |
| Chevrolet / GMC W4 (rebadged) | 4HF1 | 1987-1994 | North American market |
This feed pump also fits 4HG1 engines (the later 4.3L variant) and 4BD1/4BE1 engines that use the same injection pump mounting flange pattern.
| QC Item | Verification Method |
|---|---|
| Diaphragm material | Spectrometer and tensile test per batch - NBR rubber confirmed |
| Housing casting integrity | Visual and pressure decay test - no porosity |
| Inlet/outlet thread fit | Go/No‑go gauge for metric threads (M12 or M14) |
| Priming pressure | Hand primer lever test: minimum 0.5 bar at outlet port |
| Flow rate at 1000 rpm | Test bench with simulated camshaft actuation - 30-50 L/h |
| Diaphragm seal (vacuum side) | Pump inlet submerged in fuel, plunger actuated - no air draw‑through |
| External leak test | Pump pressurized to 2 bar, submerged in water - zero bubbles |
| Gasket dimension | CMM inspection of gasket thickness and bolt hole alignment |
The manufacturing facility holds ISO 9001:2015 certification. A certificate of analysis (COA) with batch traceability is available for wholesale orders. The supplier offers a 6‑month warranty against manufacturing defects.
The ISUZU NKR NPR 4HF1 fuel feed pump assembly 8-97223289-0 restores proper fuel delivery to the injection pump. Its nitrile rubber diaphragm resists modern diesel blends, the integrated hand primer simplifies filter changes, and the die‑cast aluminum housing withstands corrosion. One part number covers NKR58, NKR66, NPR58, and NPR66 chassis. ISO 9001 certified with 6‑month warranty.
Order a sample unit today to verify fitment on your 4HF1 engine - the same pump fits all NKR and NPR trucks with the 4.3L diesel.
