Just to add to my last post, and I thought that this would be the most logical place for this, I wanted to see how difficult it would be to make a full
set of these hoses using my technique.
I did make a pretty nice set with the correct 11/32" ID brake vacuum hose and 1/4" copper tubing. I first formed the copper tubing, and then, with
some sil-glide lube, threaded to hose over the tubing. In retrospect, I probably wouldn't compete the copper tubing bends, just start them so as
to make getting the hose on a little easier.
I have attached an image of the hoses with the ones I made in the foreground and to the right. The vac side hose in the back of the image is an
NOS rubber vac hose I used to replicate. I trial fitted both hoses to my car and the fit was perfect, as far as I could tell.
My experiment successfully completed, I am offering these to anyone in need of a set of early mastervac hoses for the cost of mailing.
Please PM me with your response, and I hope that this may help others on this forum.
