I searched the threads for help on this and mostly found only rantings of whether 134 or r12 was better. basically I know I must have a leak somewhere and want to convert it to 134A. I'll need to know which hoses and o-rings, ect. to replace as well as what to use to vaccumm my current system. If you think you can help, please feel free to contact me directly or with a simple reply. thanks
