Making Life Easier
Anything that makes life easier is a good thing. Here are a couple of GM parts that do just that.

The injector fuel line set shown above was removed from a 1998 6.5TD, and shows a novel idea the GM engineers came up with to make it easier to R&R the injector fuel lines, or for any engine project that requires the removal & replacement of the intake manifold.
The plastic fuel-line isolators shown in this photo can be used to replace the earlier rubber and metal clip arrangement used on all 1996 and earlier 6.2/6.5 engines. The new isolators are used without any other sort of clamp, and once snapped onto the fuel lines, just hang in free space between the runners of the intake manifold.

Anyone who has R&R'ed the intake manifold will tell you that R&R'ing the earlier style fuel-line isolators is a royal pain (shown on the right side of this photo). I have struggled with the original metal clips and rubber isolators several times through the years. Seems the metal clips always get a little bent out of shape, and the rubber isolators squirm out of position just when you get the clips onto the intake manifold bolts. I know I've cussed them...
These plastic fuel-line isolators are available for $3.30 each (you'll need four of them), and should be replaced each time they are removed. The plastic won't likely ever break while in use, but attempting to unsnap the plastic clips could cause them to break if they have been in service for any length of time. However, since the new plastic fuel-line isolators won't need to be removed for either an injection system or intake manifold R&R, you'll probably never need to replace them. GM part #12554808 (Fuel Feed Pipe Clip)

Beginning in the late 1996 model year, GM began using 12-point nuts that bolt the injection pump to the front cover. As anyone knows who has R&R'ed a fuel injection pump, getting a 15mm end wrench on these nuts takes a little patience, and it seems as though there are very few good positions for the wrench when using a hex nut. These 12-point nuts double the ease in finding a good position for the wrench, and they fit all 6.2/6.5 diesels. These are available from your local GM dealer for about 30 cents each....
