Heavy truck spin-on fuel filter

SGL2000204 612630080087 FF5740 FUEL Filter  The SGL2000204 fuel filter, cross-referenced OEM number 612630080087 and equivalent to Fleetguard FF5740, is a professional spin-on diesel fuel filter specially designed for Weichai WP10 and WP12 series heavy-duty diesel engines. Adopting multi-layer high-density hydrophobic composite filter media, it efficiently filters solid particles, rust, sludge, colloids and tiny moisture mixed in diesel fuel, providing comprehensive protection for fuel injectors, high-pressure fuel pumps and precision engine components against abrasion, blockage and corrosion. Strictly manufactured according to original OEM dimension standards, it realizes direct plug-and-play installation without modification. Widely used for Sinotruk Howo, Shacman, Dongfeng heavy trucks and matching construction machinery, this aftermarket filter features stable filtration performance, long service cycle and outstanding cost performance, which is the ideal maintenance spare part for global fleet companies, auto repair shops and engineering equipment users. Usage & Installation Method: Preparation: Turn off the engine completely and release residual pressure inside the fuel pipeline. Prepare a filter wrench, absorbent cloth and waste oil container to collect spilled diesel. Remove old filter: Rotate the old fuel filter counterclockwise to unscrew it. Fully clean the mounting base to remove old gasket residues, dirt and residual oil. Preprocess new filter: Apply a thin layer of clean diesel to the rubber sealing gasket of FF5740 filter. Never use grease, which will cause rubber aging and sealing failure. Installation: Tighten the filter clockwise by hand until the gasket closely fits the base surface, then turn another 3/4 circle with a wrench. Do not over-tighten to avoid thread damage and gasket deformation. Leakage test: Start the engine and keep idling for 3 to 5 minutes. Check the joint position carefully. No fuel leakage means successful installation. Replacement cycle: Replace every 20,000–28,000 km under normal highway driving conditions; shorten to 12,000–18,000 km for construction sites, mining areas or low-quality fuel usage scenarios.

SGL2000108 WK962/7 fuel filter  FUEL Filter  Our SGL2000108 WK962/7 fuel filter is a professional spin-on diesel fuel water separator specially designed for heavy-duty commercial trucks and industrial diesel engines. It precisely filters solid impurities, rust, dust and moisture mixed in diesel fuel, effectively protecting fuel injectors, fuel pumps and core engine components from abrasion, corrosion and clogging. Manufactured with high-density composite filter media and pressure-resistant housing, this aftermarket replacement filter fully matches original OEM size and performance standards, perfectly replacing Mann WK962/7, Volvo OEM 420799/8193841 and Sinotruk original parts. Ideal for fleet maintenance, truck repair shops and engineering machinery daily servicing, it delivers stable filtration efficiency, long service life and cost-effective aftermarket solutions for global heavy-duty vehicle users. Usage & Installation Method: Preparation: Turn off the vehicle engine, relieve residual fuel pressure of the fuel system, prepare a wrench, new sealing gasket and oil-absorbing cloth to collect spilled diesel. Remove Old Filter: Twist the old fuel filter counterclockwise to unscrew it from the filter base, wipe the mounting seat completely clean to remove old oil residue and dirt. Prep New Filter: Apply a thin layer of clean diesel oil on the new rubber sealing gasket of WK962/7 filter for better tightness; do not use grease to avoid chemical reaction. Install the Filter: Screw the new filter clockwise by hand until the gasket closely fits the base surface, then tighten it 3/4 turn with a wrench (Do not over-tighten to prevent thread damage or gasket deformation). Inspection & Test: Start the engine and idle for 3-5 minutes, check the joint for fuel leakage. If no leak appears, the installation is completed normally.   Replacement Cycle: Replace the filter every 20,000 – 30,000 kilometers for highway trucks; shorten the cycle to 10,000 – 15,000 kilometers for vehicles working in dusty, muddy or low-quality fuel environments.
