Unhappy Possible to change AC lines to HQ stainless-braided flex line?

Okay, my WRX is about 2.5 years old, and the AC isn't working very well. About two months ago, I noticed that the AC wasn't running very cold at all. So I purchased a can of R134-a (refrigerant and oil) in an attempt to 'racharge' the system. It seemed to fix the problem, but now the AC is performing just as poorly as it did two months ago before the recharge.

I have deduced that there is a leak somewhere in the system, and I suspect it is somewhere along those lines that are closest to the firewall -- I'm guessing somehow damaged by the installation/presence of my Cusco strut tower brace.

How do I find the leak?

How do I repair the ruptured aluminium tubing (assuming I can find the leak)?

Can I replace the entire fragile aluminium tubing assembly with some flexible, durable stainless braided hose (like the kind used for brake cables, just bigger)? Or will the refigerant have an adverse reaction to the type of rubber that is usually at the core of those types of hoses?

any help or info will be greatly appreciated

thank you

they sell specific hoses made for the a/c refridgerant. However, I dont know if they offer it stainless steel braid in the sizes you would need.

Default thanks Kaos

thanks Kaos,

I looked into it and eventually ended up here:

They seem to have everything, including a replacement charge port:

I believe that the original target market for these parts were for people who had cars not originally equipped with AC systems (older cars, scratch-built hot rods, etc.).

It looks like someone could conceivably replace that entire cumbersome hard-tube assembly by the GDA/B's firewall and make more room for strut bars, water-spray kits, whatever, really.....

Don't waste your money on "stainless braided hose" for the ac system, if there even made, which is unlikely.
If you don't want to take your car to a repair shop to have them track down the leak, try a can of ac stop leak.
