Description

What does a manual feed pump do?

This manual feed pump serves as a critical component within the low-pressure section of a diesel fuel system. Its primary function is to facilitate air bleeding and fuel pre-filling, ensuring that air bubbles are removed from the lines to prevent engine stalling or difficult starts. Constructed with high-strength components, it is built to withstand the demanding pressures and environmental conditions found in heavy commercial vehicle fuel systems.

Compatible vehicles and engines

This component is designed for use in heavy commercial vehicles, including trucks, buses, and tractor units. It functions effectively within the fuel delivery network alongside the fuel filter and injection pump to maintain consistent pressure. It is compatible with LASO systems.

Installation and maintenance

For optimal performance, technicians should inspect the pump during routine fuel filter replacements. Ensuring that all connections are tight and that the plunger mechanism moves smoothly prevents vacuum leaks. Regular checks help maintain system integrity and prevent air ingress into the fuel lines.

Troubleshooting and selection

Proper selection of this priming pump ensures reliable cold starts and stable idling in diesel engines. By maintaining a consistent flow during the priming process, it protects high-pressure components from premature wear caused by air pockets in the circuit.

OE cross-reference

0101 098 (Manual Feed Pump) is the equivalent of the LASO OE number. This part directly replaces LASO OE number 20090102.
