Thanks for the replies....

The connect from the gauges is literally a screw on. It looks like to me that they are for a different attachment.

I added a pic with the gauge connection next to the red high side on the car. They don't even come close to fitting. Makes me think it is the wrong hose attachment??

I bought them 2 months ago online when I ordered something else. There is a 90 day Guarantee Certificate in the case. I'll bring it into the store and see what they say.
