hand pump

The hand pump is a practical component in the fuel system, primarily used for bleeding or priming fuel. It is commonly used in diesel engines and facilitates filling the fuel system after maintenance or fuel filter replacement.

After work has been carried out on the fuel system, air can enter the lines or components. This air must be removed so that the fuel pump and injection system can function correctly again. Fuel can be manually pumped through the system using the hand pump until all air bubbles are gone.

Hand pumps are often located near the fuel filter or are integrated directly into the filter housing. By repeatedly operating the pump, fuel is drawn from the tank and delivered through the lines to the injection system.

The pumps typically consist of a robust housing, a flexible pump bulb or piston mechanism, and fuel-resistant seals. These components are specifically designed for continuous contact with fuels, as well as for temperature fluctuations and vibrations in the engine compartment.
