Shows boost only in reverse

For some reason my car is only showing boost when my car is in reverse. Obviously i have a major leak but cant find it. The only thing i could think of is a hose coming out right under my supercharger snout that is open. Does anyone know where that is suppose to go. Thanks in advance.
 


Yeah. It goes back UNDER it. Look for the "T" Fittings. Most likely it is rotted and you'll have to get a new set, which you can get for less than $30 from a local dealership...should be called the EVAP Vacuum Line System or something like that.
 
you have disconnected vacuum lines and you wonder why youre seeing no boost? how does that thing idle? like junk i bet.
 
they broke mine when did the recall smh and didnt bother fixing it, so i left skid marks after i picked the car up after i paid for that line. if its not cracked just replace the t with some from autozone they have some that match up almost exactly to oem specs

The autozone T-Fittings suck epic balls.

Just go to the dealership and do it right the first time (meaning BUY the part FROM them, dont have them touch it) that way it won't rot on you again...or at least it wont for like 10 years or something :p

and what exactly are "epic" balls?
 


^^ Yup, GM number is 24508742

If you pay over $22 then you're getting ripped off....but it is a whole new line from the BBV solenoid all the way back to the MAP sensor.

Install and enjoy.
