Hi all,
I have a model 5 that has a kitfox factory heater kit in it.

I am trying to find out what size/ type of fitting the barb is ? , that attaches to the heater rad and goes thru the firewall.

I can only see hose and firewall blanket with it hooked up right now.

I am going to install a cockpit controlled shutoff for the heater and will require to put a 90 degree elbow on the heater rad at the firewall exit. I would like to have all my fittings and supplies on hand before I drain the coolant and change all the hoses and such.

Thanks
