Howdy everyone, I've searched and searched til my eyes started to bleed and cannot find the answer to my question. I was wondering if the vac line that runs from the lower part of the ka24de intake manifold next to the brake booster vac line can be used as a source of vac for my blow off valve. I sure did use vac alot in that last sentence.Thanks in advance.

FPR is the most popular choice.
