Review on 🔧 Stens 520-568 Kohler Fuel Pump, 52 559 03-S by Todd Calloway

Used on a 20 year old hand mower. You must read the instructions to understand how to insert the gas line adapters. That's what the big O-ring is for. There are 2 small square release buttons for each adapter. You will need to unroll the o-ring and place the ends on both buttons to make it easier to attach the adapters. After that the rest was pretty easy. With the new pump I don't have to fill the carburetor with petrol. more to start and the lawn mower works great. The price definitely beats what the Kohler website is asking for!
