Part Number: 17/400300
Type: Mechanical, Diaphragm
Product Description:
The 17/400300 fuel pump is a critical component of the fuel system in JCB backhoe loaders. It draws fuel from the tank and delivers it at low pressure to the injection pump. Its robust metal construction and precision diaphragm mechanism ensure stable pressure and reliable fuel flow, supporting smooth and consistent engine performance under all operating conditions.
Role in the Machine & Fault Diagnosis:
The fuel pump is essential for engine operation. Common signs of wear or failure:
Service Recommendations:
Whenever the fuel pump is replaced, always replace the fuel filters (primary and main) to protect the entire system from contamination. Inspect fuel lines and replace if necessary. High-quality REDX brand filters are recommended.
