I have a 1979 USA Spitfire single Stromberg engine. The steel heater pipe that passes through the aluminum inlet manifold is perforated. I know there are places in the UK (TSSC, Rimmers) that will remove the rusty steel pipe and replace it with a new stainless steel pipe. The European heater pipe configuration is different from the USA version that I have. I attached a pic with indication of heater pipe and leak in yellow.
Are there any recommendations for where to have this done in the USA?
thanks
