Hand Pump Type Fuel Filter Assembly R20P OilWater Separator for Excavator A direct replacement fuel filter and oilwater separator assembly designed for excavator fuel systems. The R20P hand pump type unit enables manual priming and continuous separation of water and contaminants from diesel fuel, protecting the engine fuel system and supporting reliable operation in field conditions. Key benefits Effective water separation and filtration that helps prevent injector damage and fuel system corrosion. Hand pump design allows quick manual priming after maintenance or fuel changes, reducing downtime. Simplifies routine service and fuel system maintenance by combining filtration and water separation in a single assembly. Robust design for heavy equipment applications to withstand typical jobsite conditions. Product highlights and attributes Model: R20P hand pump type fuel filter and oilwater separator assembly. Intended use: Excavators and similar construction equipment requiring fuel water separation and manual priming. Size: As shown. Function: Removes water and particulates from fuel, provides manual priming to fill the system and expel air. Performance: Designed to improve fuel cleanliness and support consistent engine performance under load. Serviceability: Accessible hand pump and drain points facilitate water removal and filter replacement during scheduled maintenance. Typical applications and use scenarios Field maintenance after a fuel filter change: Use the hand pump to prime the system and remove trapped air before restart. Postrefueling water removal: Separate and drain collected water after refueling with uncertain fuel quality to avoid injector contamination. Preventive maintenance on construction sites: Install as part of routine fuel system checks to extend component life and reduce unscheduled repairs. Compatibility and installation notes Designed for excavator fuel systems; check physical size and mounting against the existing assembly before installation. Size is provided as shown; verify fitment and hose connections on your equipment model prior to . Installation typically involves inline mounting on the fuel supply path and connecting fuel lines according to equipment service guidelines. This R20P hand pump fuel filter and oilwater separator assembly is intended for use where reliable manual priming and effective water removal are required to maintain excavator fuel system integrity and uptime.
