Source for heater motor brushes?
 

Does anyone out there know of a source for the motor brushes in the heater motor pump? Mine are nearly worn out and this would be a good time to replace them. None of the electrical parts stores seem to carry them. I may have to cannibalize an old hedge trimmer in the garage. Assuming it has brushes!

From what I understand you can get the brushes at RadioShack. You may need to sand down one or two sides but I was told they will work.

That's what I have done in the past, find something close but larger and sandpaper the soft carbon to the correct size.

Grainger has a bunch of them. You might be able to find something pretty close there.
