Question and Answers


Craftsman riding mower


Thank you for your question on the Kohler engine fuel pump leaking fuel.

I think the problem is with the engine crankcase breather not working correctly and causing the diaphragm to rupture.

The crankcase vacuum and pressure operates the diaphragm in the fuel pump.

The reed breather is in the vee between the two cylinders on the engine. I would suggest examining them to see if one is broken or not opening.

Please let me know what you find out.

I hope this will help.

Sam A.
