1979 F250
1979 F250 4x4 400/c6
New compressor
New dryer
New expansion valve
1 junkyard hose from the condenser to the expansion valve. The truck was sitting for a few months, and released air when i removed the hose so i figured it was solid.
I rented a 1.5cfm vacuum pump and gauges from AutoZone.
I have replaced all orings.
I am 864 feet above sea level, Pasadena, Ca.
I have worked through this for about 3 weekends. I have put the pump on it for about 2 hours at most, and can only get down around 26.
I "retrofitted" for r134, consisting of changing orings and adding fittings.
I have never done any a/c work before. I bought a Haynes Automotive Heating & Air Conditioning book and have been going by that.
I have the pump on it right now, reading 26. Been there 1 1/2 hours.
Whats the next step?

I was out there long enough to blow the fuse.
I dont have a heater control valve installed, i replaced the hose and the cv was so corroded that i just put a straight hose. I have one ordered. Is not having it going to affect anything?
