[TR] Question on Fuel pumps TR3-4

[Doug Mathews]

Thanks for all the input.

Given the age of the new ones I have (gosh knows how long ago I bought 
them). Woulld there be any markins on them that would tell me if they 
are AC or not. Says made in Canada. There is a stamping of "AC10") on them.

Just trying to figure out what I'm dealing with.

Thanks

Doug
