What SIZE (# 6,8,10) are the AC Lines on a 87 Fiero ?

All of the above.

What size is the hose From the" Comp to the Car" that needs the" Fitting' (shrader valve) for the computer to do it's thing ? At the back, on a 3800SC swap, not up front at the canister. what size does the "T" need to be to fit the correct Hose ? Thanks
