YOU GENTELEMEN HAVE SOME GOOD IDEAS BUT WHAT ABOUT INSTALLING THE COMMON 64 TO 66 CORE GO TO THE PLUMBING SECTION OF HOME DEPOT OR A HARDWARE STORE OF YOUR CHOICE AND BUY TWO INEXPENSIVE 5/8 INLINE BALLCOCK VALVES & INSTALL THEM ONE IN EAC HEATER HOSE . BIG DIESELS USE A SIMILAR SET UP IT IS SIMPLE & IDIOT PROOF .
