Hi Geof

No , the tube is soldered along the outside of the pipe.

As stated before it can be fitted to the pipe or to the radiator wherever suitable and allows the use of the adjustable control with no intrusion into the cooling system.

I have had this system on my 40 for 3 years and on previous 4wd cars that have had V8 conversions with no problems.
