How to replace a riding lawn mower fuel filter
This step-by-step riding mower repair guide shows how to replace the fuel filter in a riding lawn mower. The fuel filter keeps dirt from getting into the carburetor. A clogged or dirty fuel filter doesn’t let enough fuel reach the carburetor, so the engine run roughs or stops running completely. Remove the old fuel filter and install a new one when you tune up your lawn tractor each year, using a manufacturer-approved lawn mower part.
This procedure works for common Briggs & Stratton engines that power Craftsman, MTD, Husqvarna, Murray, Toro, Troybilt, Snapper, Yard-Man, Ariens, Poulan and John Deere riding mowers and lawn tractors.
This video explains how to replace the fuel filter on a riding lawn mower.
