Pro Stock without giant hood scoops and big honkin' carbs ... replaced by electronic fuel injection and smooth hoods?!?!

Any ideas on how to secure the water temp sending line? - PROBLEM SOLVED

I am still trying to stay with keeping everything as much like back in the 60's as possible, including using the OEM water temp sending line (which is a metal tube to the factory gauge in the dash).
