Hello! I have recently bought a boost gauge for my 2015 VT and i am looking to tap into a vacuum line in order to get readings. Which line would work the best for what i am trying to accomplish? I have seen other threads saying to use the line coming directly from the top of the throttle body. It’s about 6” or 7” and looks easily replaceable if something goes wrong. I do not wish to buy a throttle body spacer because i simply think it’s not worth it lol. If there is another line i should tap into please let me know! Here is the line i was going to tap into soon:
Automotive fuel system Motor vehicle Automotive design Automotive tire Automotive exterior

You'd have to T below the check valve.

Not a good idea to use this hose However as it has gas vapor from the tank going through it. If this were to leak into the car somehow it could lead to a dangerous scenario. If your boost/vacuum hose does not go into the cabin then you're good to go. I do not suggest cutting the hose to T in though but rather use a small/short hose to the T then connect to the oem hose.
