A key component of the fuel system in modern JCB engines – a NEXGEN mechanical fuel lift pump. Designed for JCB Dieselmax and JCB EcoMax units. Its function is to deliver fuel from the tank to the engine's high-pressure injection system, ensuring consistent performance. A robust metal construction (cast aluminum) with steel fittings ensures durability and vibration resistance.
In the construction industry, machine reliability is the key to success. That's why we offer high-quality replacement parts for construction machinery that meet the highest standards of durability and performance. Our products are the ideal solution for companies and specialists looking for reliable components at attractive prices.

The list above is for reference. Fitment is dependent on the engine model (JCB Dieselmax or EcoMax).
Before working on the fuel system, ensure the engine is off and cool. Diesel fuel is flammable. Work in a well-ventilated area, avoid sparks and open flames. After replacement, you must bleed the fuel system.
The lift pump is the first part of the fuel system, transporting fuel from the tank to the high-pressure pump. Its failure will cause the engine to stop due to fuel starvation.

They have a completely different construction, mounting, and flow rate. They are for different engine blocks. A Perkins pump (e.g., 17/912400) will not fit a Dieselmax engine, and vice versa.
2. Why must I replace fuel filters (e.g., REDX filters)?Contaminated fuel is the main cause of lift pump failure. If the old pump has failed (e.g., seized), debris might be in the system. Installing a new pump without new filters is a direct way to destroy it immediately and void the warranty.
3. My engine is hard to start. Is this pump the cause?It's very likely. If the internal check valves or diaphragm in the pump are leaking, fuel can "bleed back" from the system to the tank. This causes the system to lose its prime and requires long cranking for the pump to re-suck the fuel.
