A/c headache's

Hello and help lol. I have a 1993 f150 with a 302 e4od trans and I was trying to fill my a/c so like usually I do is unplug the lower pressure sensor and jump it with a paper clip so it will fill but it's not taking it I geuss the high side is getting cold along with the canister where you fill it at is cold but no a/c even tho my gauge says it's full I noticed that when I touch the low side line it gave me first degree burns on my hand it was so hot but again the high side is cold and compressor is on with paper clip. all new lines and truck has been well kept all its life and maintenance properly by previous owners. 87000 is all it has for miles which is really low. Any help would be a blessing

You had the system open to install the new lines did you replace the dryer, check the orifice valve and then pull a vacuum for an hour or more?
It also sounded like you were trying to add to the high side it need to go in the low side.
