Would like to find out a little more on this obscure, but common, part. P/N 26605 Was it used outside the assembly plant for timing at all? It's buried on page 109 on Stanadyne's side.
The inline device is a piezoelectric trigger that works with a strobe.. I thought there was a special timing light deal for these at one time. TT1000 maybe? I can't remember.
I have seen sensors that hook to the injection pipe, then a timing light can be used. I just had never heard of a timing fixture added on from the factory.
Guess I should get out more. LOL
