BMT Posted July 8, 2006 Share Posted July 8, 2006 The pictures in the ebbo.org link show the current state of play. The modified parts set has been through a couple of iterations: the ADV link has the intermediate version. Don't forget you need a 15 mm combination spanner (ring/open end) to tighten the new part. The old part is 17 mm -- a more commonly found size. Be careful with the air tube o-rings. I had a spare available and I needed it. Link to comment
