Reliable fuel delivery is the heart of your engine's performance. When your JCB Backhoe or Perkins-powered machinery starts losing power or struggling to prime, the fuel lift pump is often the culprit. We provide heavy-duty 2641A053 (also known as 2641A053) and 4222108M91 replacement solutions designed for 4-cylinder engines requiring a robust 4-bolt mounting configuration.
Our units are engineered to meet or exceed OEM standards, ensuring your equipment stays on the job site instead of the repair shop.

If your JCB 3CX with a Perkins 1104 engine is starving for fuel, check the 2641A053 lift pump. A ruptured diaphragm or clogged internal valves often prevent the pump from pushing fuel to the injection pump. Replacing the unit with a fresh 4222108M91 restores optimal flow and prevents air ingestion into the lines.
Look for fuel leaking from the weep hole on the pump body, or a "spongy" feel when using the manual priming lever. If the engine takes longer to start in the morning, the internal check valves in your 2641A053 may be failing, allowing fuel to drain back into the tank.
Our 2641A053 features an OEM-standard tri-metal structure for superior heat dissipation and mechanical strength. Trusted by repair shops and equipment fleets worldwide, it ensures your 4-cylinder Perkins engine maintains peak torque.
