Sticky Fuel Pump Switch

[MichiganMooney]

My electric fuel pump switch on my '77 M20J does not work when the temperature is below 40 degrees.  It is impossible to turn on.  When the cabin warms up, it functions normally.  Is there anything that I can do (such as lube) instead of replacing it?

 

Thanks,

I would use triflo

Where is the best place to buy Tri Flow?  Can you buy it in a store?

Bicycle shops carry it.

Any of your local bike shops should have Tri-Flow.

Ace Hardware usually carries it, as well.

It can also be ordered from Mcmaster Carr in both spray and small bottle. I would personally replace the switch.
