Peggy,I am in the midst of upgrading the head-holding tank system and am following guidelines you gave me earlier this year. I have a couple of questions I hadn't thought of until I got my hands dirty (no jokes, please) this afternoon. I want to remove the small vent lines which are located fore and aft on the sides of the tank, place them on the top and make them larger. I reached inside the tank to try to determine how to disconnect the fittings, and they appear to be welded or glued into place. I don't foresee any problem removing them unless they can't be loosened. Are all factory-installed fittings threaded into the tank? If not, how would I go about cutting new threads into a 1/4" tank wall? I have done household plumbing and cut threads onto black and galvanized pipe, but never yet had to cut threads INTO a tank. I suppose I could find a nut that would thread onto the plug and draw the plug up tight with the nut on the inside of the tank.I plan to use twin vents again only larger (1 1/2"),running the forward one out at the port bow and the aft one at the starboard bow. Per your advice, I have to do this because I am going to have to install the vent thru-hulls higher on the hull than a 45 degree angle, and I want the advantage of cross ventilation to compensate for the steeper angle. Is there a rule of thumb for locating the thru-hulls distance-wise aft of the bow? Before I get my hole saw out, I want to be sure that I don't put it too far forward or aft.Other than that, everything has gone well. I have installed the new inlet hose and properly vented it. The wiring for an Accugage is in place and all there is left to do is install the sensors.Thanks again for your help. I think I told you this once before, but it bears repeating. I read so much good information at this site, but it doesn't get real until I start to do something. Then old-timer's disease sets in and I have a hell of a time remembering ( or finding) the info. The fun really starts when I start bending my late fifties model body into the proper contortions to do the simplest job on the boat. I swore off swearing though. Nobody hears it but me, and I sound pretty stupid chewing myself out
