well there is a thread discussing what you want to do excatly in here somewhere.
anyways you should have a small coil of cap tubing infront of the compressor.if not you will have to unwind some of it around the larger tube.then take 8 or so inches of copper tubing and bend yourself a new section that will connect to the tube at the compressor and put your bend in it,then reconnect to the other tube,this should give you enough to do what you need to do.if you are carefull you wont have to cut the cap tubing.

number one thing.think of all possablities before you make the first cut.

have fun
