SR Boost Gauge/Controller Feed

Hello, Hope everyones keeping well in Isolation and working on your S Body's!

Asked this on another page regarding where to branch off for the Boost Gauge on an SR,

Can you go off the front of the plenum and then branch off from 1 to 2 lines, 1 feeding the gauge and 1 for giving you the line to the boost controller for the read out? Or do you have to pipe them to 2 different feeds?

If they have to be separate, where do people recommend the best 2 place are to branch off from?

TIA!:)

Charcoal canister lines are a good source and then you can sack off the rest of it
