Review on 12-559-02-S Fuel Pump Kit: Replace OE 12 559 01-S 12 559 02-S for Kohler CH11-CH16 CV11-CV16 CH410 11-16 HP Engine by Mike Walters

Black plastic hose fittings have overly complex push-to-connect fittings that are just rubbish. Smart junk, but they don't last at all. Mine drains the fuel back if it's been idling for a day, so you have to remove the pump and manually prime it before each use. I put the old pump back in. I would like my money back for this but of course it took too long as I tried to get it working for a few weeks before giving up.
