Got a measurement on the washer?  http://www.imperialinc.com/grp310.shtml

leak. I took two apart and the electronics is fine. The contacts on 
the connector had coolant corrosion but this cleaned up easily with 
Contac-Renu. My guess is that the copper washer fails after some 
time and a very small leak occurs (2 reservoir inches per year). 
Does anyone have a source for compression copper washers like these? 
Must be a generic metric part.

(The electronics inside the MFTS contains an active analog chip. 
Simple resistance checks at the connector are not likely to be 
conclusive.)
