Thad's Tip: To prevent leaks into the motor compartment of your Shurflo 9300 Solar Water Pump which can damage the motor, use plenty of Silicone Grease on the canister o-rings and pump head o-rings. Shurflo 9300 O-Ring Kit 94-142-00 come with grease packets. These are also available on this website as part 10-1550.
