91' 740

I bought one of those cheap r134 recharge kits (I know
I already read the faq- apparently those are not
recommended) I just want to get some quick relief.

On the metal canister near firewall, there is a little
black capped valve with a P printed on it. There is
also a red capped valve with an H printed on it (Im
guessing that is the high pressure side)

I looked at the compressor, there are two ports, one is
completely inaccesable the other can be gotten to.

The problem is, the valve connector on the 'kit' only
fits the valve that has the red cap on it by the canister.



Is there another valve somewhere.. ie the suction/low
pressure side, or is the connector on the kit not the
right size to fit any of the other valves I discovered.

If ya'all could be of some help that would be great!
Thank, Jon
