Which (R12) valve core is high side?
Long story short- when converting my 92F150 from r12 to 134 i took out both valve cores (ya i know only the low side is suppost to be removed) and now i need the high side back in. The conversion fitings have a core built in the low side but not the high. They old cores are different- one is blue and one is black. My ? is which one is the high side service valve core
Both R12 service valve cores.
