Review on 🔧 High-Performance Fuel Pump Replacement for Kohler Engines: K241 K301 K321 K341, 10-16hp, M10 M12 | Replaces 4739319-S, 4755901-S, 4755903-S, and more! by Matt Welch

Diaphragm pusher has come loose where it goes through the diaphragm. After standing overnight, he refueled the engine with gasoline. I'm a truck and heavy equipment mechanic. I disassembled it to investigate the problem. Very bad production. It cost me about 10.00 for an oil change, labor and a trip to the UPS store to return it. How many defective ones did they build? I am looking for another supplier. Through Simplicity it costs 184.00!
