You have to remove the oil line from the oil filter housing. To do this you must push the line into the housing and use something to push the plastic quick connects into the housing and then pull the line out. I used a pair of needle nose pliers. This one was a real pain to do and when you reinstall the new lines and quick connects, when you think you've pushed the line in far enough keep pushing. It will give a good snap when it goes all the way in. This was on a 94 Chevy Fullsize Blazer and also 91 silverado.
Depending on where the leak is, if there is a weakness in the 350 it was with the oil cooler lines. It turns out that most of the oil leaks from the cooler lines has nothing to do with seals. It's a problem with the cooler line.
You can buy a replacement cooler line assembly that goes between the oil filter and the radiator. I believe Autozone can get this buy order. Takes about 30min to replace.
The oil cooler isw up front in a suburban. Get a drain pan and a shop rag. Get under the vehicle with the line wrench to take the line from the cooler off at the radiator. Unbolt the cooler from the frame and take off the line from the transmission. If you are replacing the hose only or repairing it, just remove the hose and replace. Oh! and be sure to replace any fluid loss in the tranny with the correct fluid which any parts store would know.
Go slow. Don't take the WHOLE thing apart. Just repair the oil cooler first and see what leaks. The 350 tends to have problems with the o-rings on the oil cooler line. Repair that first if you aren't absolutely certain that oil isn't just leaking on everything else from the cooler. On the other hand, if you're ABSOLUTELY certain that you have to replace the oil pan gasket, you'll need to raise the engine to replace the gasket. To raise the engnine, pull the motor mounts and lift the engine 4 to 6 inches, then you can pull the pan bolts and drop the pan.
Yes there should be one on both ends of the line.

Yes you do.
Yes. There are aftermarket suppliers that offer oil coolers that use the oil pan's drain plug as an access point. INTO? Many of the 350's have an external oil cooler. It was standard equipment on pickups with the towing package, and in fact it was a bit of a problem for a few years since the engine oil coolant line often leaked when everything else was still tight.
It don't have to have it. But it will make the engine LAST LONGER.
i dont know this answers the best one in the world.
Buy a new one and install it.
