Hey neighbor! A lot of the heat under my hood comes from long tube headers and aluminum intake. I installed this return line along with a Holley aluminum carb heat shield and am no longer experiencing the stumble at idle when hot or long start times after the car has sat for 20+ minutes after driving. The return lines flows real well and keeps the fuel cool in the lines now. I am using a Stant locking fuel cap that I removed the spring relief out of so it breathes with no pressure build up.
