Recharge A/C Diagram???

[Hangfire]

Is there a diagram that shows how to recharge the A/C unit on a '91 22re? It's a tight fit and I'm not sure which valve gets the shot.

Any help greatly appreciated!

trace the lines back and look for the fat one.

On Top of The Compresser there is two outlets. The High Presure Line runs upward toward the back along the Intake manifold to the FireWall.The Low Presure side is the Short Fat Line Running low to the Front of the Vehicle to the condenser. the Low Presure line Is were you charge the system.

But You might want to consider this before starting.

Pickups (Except 1995) A/C system has R-12 Refigerent. You can't buy R-12 unless you have a License to buy it. And I believe right now it's $60.00 for a small can.
The best thing is to do is Convert from R-12 to 134-A Refigerent.

Have you guys heard of the Freeze-12 yet? It is a direct replacement for R-12.....no conversion kit needed. Cools better than R134a also.
