Todd,

What about = the=20 electrically operated valves (see list from Paul).  It looks like = it=20 would be easier to install in that you don’t have any control = cable running=20 through the firewall.  And you won’t have the cable = sticking out into the=20 cabin, just a switch. 

 

Mark = S. =20
