This engine takes water from the radiator lower pipe and feeds it into the back of the engine via a stainless steel pipe. The standard Omega one is quite bulky and wants to occupy the same space as the steering cone on a right hand drive car. This pipe is essential for the running of the engine therefore needs to be re-made in a way that fits the MGB engine bay. I chose to make mine using very carefully cut and welded stainless steel tube. It needs to pass underneath the exhaust headers so can’t realistically be made of anything that will burn or melt.
