Turbo0000 New Member 15 Member For: 3y 8m 21d Posted 06/07/20 11:34 PM Share Posted 06/07/20 11:34 PM (edited) Apologies for the noob question. I have a ba xr6t and a boost gauge to install, yet I have no bov. I was wondering where to install the t piece as usually it would be connected through the vacuum line from the bov if I'm correct. But since I have no bov, I'm lost Edited 06/07/20 11:35 PM by Turbo0000 Noob* Link to comment Share on other sites More sharing options...

If you can find that you can just use that. 2 Link to comment Share on other sites More sharing options...

Am I missing something? Link to comment Share on other sites More sharing options...

Post a pic of the back of the gauge and the vac line you found. Link to comment Share on other sites More sharing options...

Then just cut a vac line under the bonnet and connect those to each end of the T. I'll grab a photo later if the sort of thing you are looking for.That BOV you have taken a photo of is the actual air path for the BOV, not the vacuum line that controls operation of the valve. There will be a much smaller line floating around somewhere that been blocked off as well. You see the size you are looking for when I grab a photo. 1 Link to comment Share on other sites More sharing options...

Wouldn't be the end of the world if you did, but don't. Link to comment Share on other sites More sharing options...

You'd have to still reduce it down to the size of that new line though, using the T.So you could plumb the gauge to the t with the supplied line. Then connect some vac line from the spot where the bolt currently is to the T. Then a bit more line off the T that you then block with a bolt. For reference, this is what a BOV set up looks like with a vac line to control the valve. Link to comment Share on other sites More sharing options...
