Kohler 5EKD generator fuel pump module leaking

oscar1

I have to replace the fuel pump module($647.59) in my 5EKD because the gasket has small fuel leak, but the module still in great condition, so I wonder what material should be the best to use to make a new gasket to the repair of the fuel pump to keep it as spare part for the future. The original gasket is 1/16" thickness, so should i use the same thickness or go higher to 1/8" for the new gasket. I called Kholer, but they don't t sale any repair part for the pump. Any ideas will be appreciated. Thx.

Take that gasket to a good auto parts store or shop and get the material matches or equivalent and then trace and cut. In my area I would use NAPA but not sure what you have locally. 

There is liquid gasket in a tube that might work. Hard to say without feeling the material. 

Worth a shot at spending maybe $10 and some time before you drop $600

The base gasket material is not the concern. The silicone or viton seal portion is (the trace lines you see). Those are what do the sealing when compressed.

I agree, maybe find a sheet of fuel safe silicone or rubber material. Or use a thicker gasket material with a good fuel safe sealant.

Can the silicone or viton seal portion add to the gasket during installation?

@oscar1: short answer: no.
