Isuzu 4JG2 Diesel Fuel Injection Pump 104646-5051 – Zexel NP-VE 4/11F1200 Forklift OEM

Isuzu 4JG2 Diesel Fuel Injection Pump 104646-5051 — Zexel NP-VE 4/11F1200LNP2293, Forklift OEM

This is the Zexel NP-VE rotary distributor-type fuel injection pump (part number 104646-5051, model NP-VE 4/11F1200LNP2293) for the Isuzu 4JG2 3.1L turbocharged 4-cylinder diesel engine, used in Isuzu forklifts from 1992-2002. The NP-VE (VE-type) pump is a single-plunger rotary distributor pump — different from the inline multi-plunger pumps on larger engines. The single plunger both pressurizes and distributes fuel to each injector in sequence through a rotating distributor head. The VE pump is lighter, more compact, and capable of higher injection pressures than older inline pumps, making it the standard choice for medium-displacement diesel engines in forklifts and light trucks.

This 4JG2-brand OEM pump is manufactured in Zhejiang, China with 100% professional testing and a 6-month warranty. Standard size, 6.2 kg gross weight, 30×30×30 cm wooden case packing. MOQ: 1 PC. Payment by TT, Western Union, or PayPal. Shipping via express, sea, or air. Also available: cylinder block and cylinder head for complete rebuilds. The VE pump’s injection timing is controlled by an internal timing device — verify pump-to-engine timing marks precisely during installation. An incorrectly timed VE pump will cause hard starting, white smoke, and poor power.

Compatible with Isuzu 4JG2 turbo diesel engines in forklifts (1992-2002). Browse our injection pump selection for Mitsubishi engines.
