Changed to adapter plate
I switched to the Colin Hyde adapter plate after testing the brass valve rebuild 6-7 times without success! I either had bolts to tight to operate slide, or to loose and it leaked! The outer gasket was too thick but was trimmed down to what I thought was a good fit.
I never want to change this valve once the tank is installed! Since tank is out, now is the time to change! Making adapter plate was easy, after buying a 3 inch hole saw.
I am also changing the black tank to one from a 63 overlander, with the tank going more to the side of the trailer ,instead of across the rear. This means more elbow room and partial elimanation of the wall cabinet. I will be rebuilding all the cabinets and the size differance is no problem.
The brass valves out of the 63 Safari and 63 overlander thou similiar , had differant connections for the grey water drains.
