I posted this in the fuel forum but I don't think it gets near as much traffic as hear and it's FI related too.

i built a tapped alimumum block that i Tee all my vacuum line fittings on it with 1/4npt, and i threaded my hobbs switch into that.

Mines mounted on the butt pipe for the incons. Seems to work good there.

Ok, a couple good options that I unfortunately don't have lol. I have the stock block and it's a procharger set-up. Is there some kind of T-fitting I can put in the brake boost line? I really don't have anyplace to thread the hobbs switch into as of right now. Where do the procharger guys normaly mount this thing?

you will have to buy some brass fittings and barbs and make a point were you can thread them in, go to the hardware stores they will have all the pieces you need.
poutting it in the brake boost line will work fine.
