Yes, I'm speaking of the water jacket side and appreciate all the input. Of course I'm trying to avoid disturbing or removing the distributor because it runs so well why mess with success??
However, that may not be possible. If I am able to remove, I think I will add some kind of extension so that the fittings are not buried behind the distributor again. I don't think you should have to remove the distributor every time you want to tighten this fitting or hose.
