Is the small valve the AC high pressure hose, it appears to be connected from the front of the radiator to the compressor, there are also 2 short hoses that go through the dryer and it has the large filler valve after the dryer. I have to replace the high pressure hose as it popped and leaked the refrigerant, I was running R134A for several months and the AC worked fine till I requested some extra R134 to be added and the hose blew! , I am the hoses are not available but where can I get a suitable replacement made? I hears someone who makes hydraulic hoses could be a source.
