Product Name: Mercedes-Benz Truck Manual Fuel Priming Pump Assembly (Hand Primer Fuel Pump with Transparent Sediment Filter Bowl)
Applicable Models: Mercedes-Benz Actros MP1 heavy-duty trucks, compatible with OM501 and OM502 series diesel engines.
Product Functions
The top knob enables manual priming. After fuel filter replacement or engine maintenance, it bleeds air from the fuel circuit to facilitate engine start-up.
Fitted with a transparent sediment filter bowl, it preliminarily filters impurities in diesel and separates water from oil. It allows direct visual inspection of water and sediments in fuel, protecting the downstream high-pressure fuel system.
It is installed at the front end of the engine fuel inlet to supply pre-fuel for the fuel system.
Common Faults
Internal pressure leakage of the hand primer knob, failing to build up oil pressure and resulting in priming failure;
Aging of the filter bowl sealing ring, causing diesel leakage;
Clogging of the built-in filter screen inside the filter bowl, leading to poor fuel supply and reduced vehicle power.
