i have a 1995 Saturn Sl1, andI'm re-charging my a/c tommorrow. I found both of the gauges, i just dont know which one's which. Now, both of the gauges have the same size dust caps, but one has a fatter tube going out and the other one has a slightly thinner tube. Which one's low pressure? thanks cheeks.

put your hand on one of them(carefuly) one is hot the other is cold
low side is cold.
high side hot.
the fat tube is low side.
the thin tube is high side.

i own a shop and the low side is the one nearest to the firewall ,or the large canister is always how remember it,and the fitting should only fit one of them,good luck hope this helps.

as soon as you pull the caps off you will see a difference, you CAN NOT mess that up, not on an r134a system
