I bought a Delta 68 pistol and there is a leak where the cartridge goes in so I know the O-ring needs to be replaced.
I've already bought a bunch of replacement O-rings, but I have no idea how to completely take apart the whole valve face thing to get the O-ring out.
I read a thread here that said I don't have to take it apart to replace it. If anyone can get me a pic of where the O-ring actually is, I'll really appreciate it. If I do have to take apart the valve face, any help with that would help.
I've tried to unscrew the valve cap to get in there, but I can't.
^Not sure if the O-ring fits in there with the puncture pin.^
^This is what I can't unscrew...^
