1104-382100C fuel filter

SGL-31945-65000 1104-382100C Spin-On Diesel Fuel Filter SGL-31945-65000 fuel filter is a professional spin-on aftermarket replacement part cross referenced with OEM number 1104-382100C, specially designed for agricultural tractors, farming machinery and small industrial diesel engines. Constructed with high-density reinforced multi-layer filter media, this fuel filter efficiently captures rust, dust, sediment, sludge and colloidal impurities mixed in diesel fuel. It provides reliable protection for fuel injectors, fuel pumps and key engine precision components against abrasion, pipeline clogging and early wear damage. Manufactured strictly in accordance with original OEM dimension standards, it supports direct plug-and-play installation without any modification. Featuring steady fuel flow performance, outstanding pollutant storage capacity and cost-effective wholesale price, it is an ideal maintenance spare part for farm repair stations, agricultural fleets and global agricultural machinery filter suppliers. Core material and internal structure: Preparation: Turn off the equipment engine completely, close the fuel inlet valve and release residual pressure inside fuel pipelines. Prepare a filter wrench, absorbent rags and a container to hold spilled diesel fuel during disassembly. Remove old filter: Rotate the old filter counterclockwise to fully unscrew it. Thoroughly clean the filter mounting base to wipe off old gasket residue, dirt and residual fuel completely. Gasket Lubrication: Spread a thin layer of clean diesel evenly on the new rubber sealing gasket. Do not apply grease, which will cause rubber swelling, aging and permanent sealing failure. Install New Filter: Hand-tighten SGL-31945-65000 clockwise until the gasket closely fits the base surface, then turn an extra 3/4 turn with a wrench. Never over-tighten to avoid thread cracking and gasket deformation that causes fuel leakage. Leakage Inspection: Restore fuel supply and start the engine to idle for 3–5 minutes. Carefully check the connecting joint. Installation is finished successfully when no fuel leakage is observed. Replacement Cycle: Replace regularly under regular farm working conditions. Shorten the replacement interval properly when working in muddy farmland, dusty field environments or using low-quality diesel fuel.
