I am searching for Yanmar part #129171-13550, a mixing elbow for a Yanmar 3JH2-TE. I thought the hard part would recovering from the shock of the quote I was given for the work to be done. Once I wrapped my mind around that and gave the go-ahead, I found that there were no such animals in the US pipeline. There are apparently a couple in Europe at more than twice the US price. Any suggestions for locating one gathering dust on someone's shelf?
