Air Gap / Autoguage Question

If you all would look at the picture BrianT posted with the fitting Crackedback linked too ....it is that simple...Dam.....LOL

just bolted an autometer adapter on to an Air Gap last night....

you can put an old stock temperature sensor in the stock location to plug the hole or use a 1/8 or maybe it is a 1/4 NPT plug to plug it....
