AC Line Torque Specs

Haven't got a manual yet and am in the process of replacing the air conditioning suction/fluid line on my 99 3500. This is the line that bolts to the back of the copressor and has two lines off of it. One goes back to the dryer the other goes up to the condensor in front of the radiator.

I need the torque spec for the bolt holding the lines to the back of the pump and the spec for the bolt holding the line to the condensor.

Also, if you could look and see what kind of seal/o-ring is used on the line going to dryer I would appreciate it. The dealer could not find anything for that end.

Any help would be appreciated as I would like to get this thing back together and charged. it's been rather warm here in the Midwest.

Thanks

PS--If you're interested in preventing a problem, you might want to ckeck the routing of your air conditioning line. The line going from the pump to the condensor was pressed against the boost duct going from the turbo to the intercooler. The constant vibration of the engine caused the aluminum part of the line to wear through where it was up against the boost duct.

I have heard that this is not an uncommon occurrence.
