It's the line that runs pretty close to the turbo, kind of at the top of it between it and the firewall. Iv'e got three choices of which it could be on GM Parts Direct.


Lwr press hose
Return line assy
Upr press hose

 

Bump!
Do we have anyone on the board that knows something besides hid's, neon kits, and what kind of wheels fit what car?

 

you wont get any help with that attitude, but none of us really have ANY experiance with those cause they dont have anything to do with most anything hahaha

 

All those terms are generic and arent what its actually called. Thats the rear half of the condenser tube. Its the high pressure "in" tube for the thermal expansion valve.

My guess is thats what they are calling the upper pressure hose, because i would say the lower pressure hose is the front half that goes from there to the condenser.

 

Awesome, thank you sir.
I believe the high pressure port is connected to it as well, but the wording on the parts description on gmparts direct kind of threw me for a loop.
thanks!
