Fuel Pump Diaphragm Sierra Marine Engine Parts 187839
Mfr # 118-7839. In diaphragm pumps, a composite membrane bends up and down over a fuel bowl The bowl has two inputs and outputs, each with a check valve to ensure only one direction of fluid flow The diaphragm raises, creating a vacuum that draws fuel from the fuel tank into the fuel bowl A diaphragm pump's main advantage is that it draws fuel from the tank Unlike other pumps, the diaphragm pump creates a vacuum in the fuel bowl, so if you run out of gas, the diaphragm pump will immediately pull more gasoline into the pump and the engine without priming Dirty fuel isn't an issue because the pump doesn't have moving parts and can't be damaged by it the engine can, but not the pump Key Features Diaphragm for Sierra Fuel Pump Mallory 935325, Mercury 80606M, and Yamaha 648244110000 are all interchangeable Check part numbers to make sure they fit correctly Specifications SKU 187839 UPC 808282259983 Weight 001 LBS Alternate Products SKU 80606M, REC6482441100, 187839 Manufacturer Part Number MPN 1187839 Fuel Pump Diaphragm fitting Mercury and Yamaha Outboard applications This product replaces 648244110000, 6482441100, 477839, 808282259983, 3099932313, 935325
