Tial purge valve requires 1/4 in. ID vacuum line. I didn't have it when I bought it and couldn't find anything locally except for a fuel line which I didn't want to use. So I just used the small vacuum tube I had as a temporary solution. BOV was not very responsive. I heard a delay when accelerating, I changed it like this and now the response is instantaneous.
