DIY: A/C Insulation

That is wrong.

The LOW pressure line is for refrigerant going to the COMPRESSOR. The HIGH pressure line is for refrigerant going to the EVAPORATOR.

Both lines should be insulated. Insulate the low pressure side to keep the refrigerant a bit cooler going into the compressor and insulate the high pressure side to prevent the refrigerant from absorbing heat from the engine bay.

Your pipe insulation may melt (I don't know how hot this line gets) if you insulate the line going from the COMPRESSOR to the CONDENSER

low > compressor > condenser > high > evaporator > repeat

Ah crap! I knew I had the idea backwards. But....I am still getting colder air.

Side Note: It's a PIA to reach that high pressure line. If I can get some kind of reassurance that it'll make a significant difference, then by golly I'll grease up my body to squeeze in there if I have to.
