Suburban A/C fix + Vintage Air?

A little late to the party but it aint that hard. LS carb'd is odd but in your favor with no ECM input for the ac & fuel system. Shame all that EFI engineering is gone.
Anyway this diagram may help you out with your lines.

Thanks a ton! Can you post the part where it shows the labels?
The wiring is the part I really need!

I would prefer to have the stock FI for sure, but I sort of get why some folks use Carbs: it's relatively simple, especially if you "get" carbs.
My Holley is not yet running to its full potential, but I'm getting there.

Thanks again for the diagram!

Here is the original Accumulator on my '76 Burb 3" diameter.
It's different than the '86 (which had rear ac).
Notice this has only one connection to it and one service port (unless it's on the bottom???):



Here is the Receiver/Accumulator for the '86:



Question is: which one should I use?
