Pollack Pete 2,273 #1 Posted February 17, 2011 I'm working on my recently acquired Wheel Horse 856 with a Kohler K-181S engine..I usually start repairs with the fuel system.I already rebuilt the carter carb.Today I took off the fuel pump.At first,I thought the pump arm was missing,then I realized it's a vacuum operated pump.Any rebuild kits available for these pumps?What size Kohler started using a mechanical pump?Thanks for any and all info.

DMK855 15 #2 Posted February 17, 2011 Pete, I am working on a K181 fuel pump as we speak. I have a kit coming for the vac. pump this week from a company in Ma. If it works, I will let you know. The kits are no longer available from Kohler. If your motor has the eccentric on the cam for the pump, you can use a mechanical pump. Replacement mechanical pumps can be had for around $45.00 give or take!! The kit (if it works) was 29.00 to my door!! Best of luck!! Share this post Link to post Share on other sites

KB9LOR 4 #13 Posted March 11, 2011 I cross referenced your number, and it is showing not found, you may have a bad part number.. Share this post Link to post Share on other sites
daemon2525 5 #14 Posted March 11, 2011 I guess that I am lost then. The original poster wanted a fuel pump for a K181 as do I. I think that the part number is 41-559-05 I am ready to buy this part. if it's not the right part number then it would be great to know that. http://cgi.ebay.com/NEW-Kohler-Fuel-Pump-K...=item415329b72a Share this post Link to post Share on other sites
