hi im in the process of buying a vacuum gauge (mechanical) in the next week or so, and ive started looking around the manifold to find a suitable vacuum line, but ive never done this before so if someone knows where the best spot to insert a T section is so i can run a pipe back to the gauge, it would be a awesome help. also any other info related to a set up of a vacuum gauge like how quick will the readings be, instant or delayed?

lines i think would work at the monument
1. what appears to be a break booster hose, heavy duty rubber hose comes off from directly underneath the throttle body.
2. close to the firewall on the end of the fuel rail their is a fuel regulator, above that fuel regulator their is a rubber hose that could be taped into easily.

thanks guys

I used the line off the fuel reg.
Reading will be pretty much instant.

sweet looks like i was looking in the right area, thanks a ton!!!
