Does the way this previous owner hooked up the boost gauge work?

The red highlighted line is connected to the boost gauge that the previous owner installed. Is this a viable way to do it? Im not getting any movement on the gauge. I have read about the circled in blue pipe plug on the intake snail. Should I switch it to that spot? 1994 factory turbo f350.

Pretty much the same, ugly? Perhaps.
The gauge is suspect, try feeding it regulated psi, 5-10psi observe the gauge.

They tapped it into the wastegate line. Yes it would work, but yeah, ugly. I put mine on the port you highlighted blue. Sounds like your gauge is a dud
