I just picked up a "Flushing Tee" kit from the auto parts store, but am kinda dumfounded on where it should go. I'm working on my 74' Chris Craft with the electric shift stringer and a 5.7. Logic tells me that it should go in the hose going from the intermediate housing to the t-stat housing, however that hose is over an inch in diameter and the largest tee in the kit is 3/4". Could I hook this up to one of the smaller hoses going to the manifolds from t-stat housing or do I have to put this into the line coming from the intermediate housing? I should also add that my stringer does not have the connection for a hose on the starboard pivot cap, hence why I bought the flushing tee.
