Default What is the vacuum hose size for stock BOV?

Anyone happen to know what the inner diameter of the vacuum hose running to the stock BOV is?

I'm going to tap it for a gauge tomorrow and I guess I'm too lazy to go and check for myself tonigh. Since I was on the board anyway... I figured I would ask. Thanks!

Drees,

What kind of connectors did you use to tap the line and where did you get them? I've had a hell of a time finding anything (brass or plastic) to tap a 1/4" line with a 1/8" t.

Thanks!

Rich

1/8" T? my old greddy T was that size i think, i just used teflon tape to build up the thickness and zip ties held it all in place, never worked itself off. you can also use hose clamps instead if you're worried about it. or else just get a 1/4" T, then a 1/4" to 1/8" coupler.

I used a 1/4" tee, a 1/4"-1/8" adapter and a couple inches of the nylon 1/8" hose that came with my Autometer gauge to hook the adapter into the 1/8" vacuum hose I used that you can't see.

I could have run the 1/8" nylon hose all the way, but it seems too easy to kink so I just used a few inches of it sticking out the back of the gauge and where I joined the vacuum hose with the adapter.

BTW, www.mcmaster.com sells a 1/4"-1/4"-1/8" stainless steel T so you don't have to use an adapter if you didn't want to. If I ever decided to re-run the line I would go that route.

Again, Thanks.

I just bought an adapter... similar to what you described... kind of figured it out from the picture. I might look into that mcmaster T though. Thanks.
