Aight here goes got a 99 ls with revhard turbo, trying to get it running but problem, My vacuum line coming off the top of the fmu has a tripple T fitting on it, Would anyone know what these lines would run to. I'm thinking one is for the blowoff valve. Also the vacuum line between the intake manifold and FPR, is that were you T fit into or am i thinking completely wrong. Thanks

 

To the Top

 

Should be tee'ed into the vacuum lines in the manifold.

 

i T into the vacuum line above the intake manifold. the triple T... lets see, theres the boost gauge, the BOV, the FMU, and the wastegate (dont know if you need to do this because your external.) right now i only have 3 Ts and i need one more.

 

just to make sure, you guys are talking about the vacuum line between the FPR and the front of the intake manifold right??? thanks

 

yes... the line on top of the FPR. the line under it is a fuel line that also goes into the FMU.
