I have an Autometer Sport Comp gauge.I have it run into the upper radiator hose. You can either buy a fancy inline adaptor or go to a salvage yard and pull one out of the lower radiator hose.If you look at the lower hose you will see the adaptor. It runs a switch for the small fan behind the bumper. Grab that, remove the switch, insert gauge probe with some teflon tape. Much easier than drilling and tapping your manifold.
