Description
Overview:
This genuine Briggs & Stratton fuel pump (OEM 597338) is a pulse‐type diaphragm pump designed to deliver petrol reliably from the tank to the carburettor on small engines. Built with a fuel‐resistant polymer housing and internal diaphragm components, it provides consistent flow and long service life. It is engineered for Briggs & Stratton vertical crankshaft side‐valve engines rated 10 HP (approx. 7.5 kW) to 13 HP (approx. 9.7 kW), commonly found on ride‐on mowers, lawn tractors, and other garden machinery. A direct replacement for older part 808656, it helps cure fuel starvation issues and supports smooth starting and steady running. Suitable for routine maintenance or a like‐for‐like swap on engines that specify 597338.
