choke/manifold heat tubes

RonS

What do you guys like to use for the insulation on the copper tubes going from the exhaust manifold to the carb choke spring( two on the twin H).Fuel line insulation diameter is a bit to wide. What looks authentic and where to buy it?

Here's what I used. The only thing different from the original is that the ends of the insulation are covered with a black coating to keep from fraying, and Hudson used a hog ring to hold the insulation onto the choke tube which limited the fraying. They come in a standard length of which one is a 1/2" too short for the front choke tube on Twin H. I just put the short side up at the carb and you cant see it because of the air cleaner.

Hope that helps!

Thanks John. Mine are original and they are getting brittle. I did the same with the ends by the carbs, but now they are about a inch short. I ordered a pair from Ecklers.
