Ok so I am still kicking around these ideas heating the manifold. I kind of like TLowe's way. Just curious though as to the size of the line used. The supply hole out of the bottom of the block is only 1/4 NPT and the holes in the manifold are 3/8's? Would a 1/2" line supply and evacuate enough water to and from the manifold? Or do I need to rig a bunch of fittings to get up 5/8th hose? Curious to know what Tom did here.
I am trying to do this while keeping the manifold heat, and cab heater on there own designated hoses. I guess it's just the analness in me.
