Boost gauge...

[WayneG99]

What vacuum line do I use for a manual boost gauge on a 2004 GTP?

[Bio248]

any vacuum line..since there is only one..

(the one that goes BBV > FPR > LIM > MAP)

Yup, and on both our GTP's I tapped into it between the LIM and MAP so it's nice and hidden in the back.

ok thanks! just wanted to make sure.

I think on his it would be BBV>LIM>MAP>MAP since they have no FPR (returnless fuel system) and two MAP sensors.

...okay you win.

So, cutting the stock vac line between the MAP sensor and the LIM is the best place? I was thinking of maybe switching out the 90* rubber connector that goes to the MAP with a T and running the line to the gauge that way. I just bought a new vac line assembly when I done the LIM gaskets and I would rather not cut into it. If my idea would not work, than just get a rubber T and cut the line and put it inline and run a plastic vac line to the gauge?

any place is good most people like it there because it is hidden out of sight, i hooked mine up last night and just ran a T and took of that 90 that you are talking about and i haven't had any problems yet

Nice. That is what I wanted to hear. Did you run a hard plastic line for the boost gauge?

yes i did

i put an extra T fitting on the MAP sensor input and continued the line into my car. realistically you can do it anywhere. i ran a soft rubber line and it works just fine.
