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.
