System does not hold the vacuum. Charged a bit with UV dye and the UV dye is dripping out at the bottom at the AC drain tube. Just to be sure, I thought (after checking there is no pressure in the lines) that I close down the AC lines after the low and high pressure points with some plugs like this:

That way if I make vacuum again and it holds it, I can be absolutely sure it is the evaporator only.

What size plugs I should get? Is there same parts already for it? I could not find.

EDIT: I was thinking something like these:

Thank you in advance!

PS: Once the lines gets some charge, the compressor kicks in, clutch is engaged, and there is no UV dye (UV light) or freon escaping (sniffer tool) anywhere else, I checked.

 

Anybody? This weekend I will get all sizes from Home Depot and try myself if no answer
