Cummins ISDe engine fuel filter

LGS2000311 FF5470 Spin-On Diesel Fuel Filter  LGS2000311 fuel filter is a high-quality spin-on aftermarket replacement element cross-referenced to Fleetguard FF5470, specially designed for Cummins ISDe series medium-duty diesel engines widely used on commercial trucks, city buses and light construction machinery. Adopting multi-layer reinforced resin-impregnated cellulose filter media, this filter efficiently traps fine rust, dust, sludge, carbon residue and colloidal contaminants in diesel fuel. It provides reliable protection for high-pressure fuel pumps, fuel injectors and precision engine internal components against abrasion, blockage and premature damage. Produced strictly per OEM dimensions, it supports direct plug-and-play installation without modification. Featuring stable flow performance, long service life and cost-effective price, it is a perfect maintenance part for repair shops, fleet operators and global filter wholesalers. Usage & Installation Method: Preparation: Shut off the engine, close the fuel inlet valve and release residual fuel pressure in pipelines. Prepare a filter wrench, absorbent rags and a container to collect spilled diesel. Remove old filter: Twist the old filter counterclockwise to detach it. Clean the mounting base thoroughly to wipe away old gasket residue, dirt and residual fuel completely. Gasket lubrication: Coat a thin layer of clean diesel on the new rubber sealing gasket. Do not apply grease to avoid rubber swelling and sealing failure. Install new filter: Tighten the LGS2000311 filter clockwise by hand until the gasket closely attaches to the base, then turn an extra 3/4 turn with a wrench. Never over-tighten to prevent thread breakage and gasket deformation. Leak test: Restore fuel supply and start the engine for 3-5 minutes idling. Check the joint carefully; installation succeeds if there is no fuel leakage. Replacement interval: Replace every 18,000–25,000 km under normal highway conditions. Reduce the cycle to 10,000–16,000 km for dusty construction sites or low-quality fuel conditions.

FF5485 BF7813 Spin-On Diesel FUEL Filter  FF5485 BF7813 fuel filter is a premium spin-on aftermarket diesel filter engineered to replace original Fleetguard FF5485 and Baldwin BF7813 elements. Designed for Cummins ISBe and ISDe series diesel engines widely used on medium & heavy trucks, buses and construction equipment, it adopts multi-layer high-efficiency filter media to trap fine dirt, rust particles, carbon residues and colloidal contaminants in diesel fuel. It delivers stable flow rate and outstanding dirt holding capacity to fully protect fuel injectors, high-pressure fuel pumps and engine precision components from wear, clogging and premature damage. Manufactured to strict OEM dimensional standards for direct bolt-on replacement without modification, this filter offers reliable OEM-equivalent performance at an economical cost, ideal for repair shops, fleet operators and global industrial machinery maintenance. Usage & Installation Method: Prepare tools: filter wrench, clean rag, collect container for residual diesel, turn off engine and release fuel system residual pressure completely. Unscrew the old fuel filter counterclockwise, wipe the filter mounting base thoroughly to clear old gasket debris and grime. Lubricate the new rubber sealing gasket with clean diesel fuel (do not use grease) to ensure tight sealing. Hand-tighten the new FF5485 BF7813 filter clockwise until the gasket touches the base firmly, then turn an additional 3/4 turn with a wrench. Do not over-tighten to avoid thread damage and gasket rupture. Start the engine and idle for 3–5 minutes, inspect the connection joint carefully for fuel leaks. Installation is complete if no leakage occurs. Replacement cycle: Replace every 20,000–25,000 km under normal highway conditions; shorten to 12,000–18,000 km when running on low-quality fuel or dusty working environments.
