Where to tap vacuum line into manifold for boost gauge?

[97AutoXVette]

Anyone have any pictures of where/what they used to supply vacuum/boost pressure to their boost gauge?

Did you T into an existing vacuum port?

Thanks in advance

T into the line going to the fuel pressure regulator as it needs to see vacuum/boost as well.

Right b4 the map sensor along the firewall put a T in. That's where mine is and I get accurate readings.

Anyone have a picture of their setup by chance?

go to advance auto, they sell these little white T's, and a foot of vac line. cut the stock plastic line that comes from under the snout to the back of the engine, push a 2 inch long piece of vac line on the cut ends of the stock line, then put the t in the middle. then the boost gauge off the open port on the T.

Good deal, have purchased and used those white T's before from Autozone. I saw another thread about where to route the vacuum line through the firewall. Any good locations you'd recommend while we are on the topic?

find a grommet under the brake booster. you should be able to push it through with the wires that are there already. try to route the line with other wires along the firewall, small zip ties work well, this keeps the line safe from being burnt or broken.

It's too late now, but you coulda searched around and found atleast 50 threads on vacuum lines for boost gauges....

Sounds like I have everything I need. Thanks for the responses. FiveFinger, I hear you. should have searched a bit before starting a new thread on a covered topic.
