Air Bleeds
Note: Air bleeds are the little plastic diffusers that go in the hole under the injector. 84-88 non turbos use a one piece bleed, while 86-88 turbo and all 89-92 use a two piece bleed (Top & Bottom). These pieces almost always break when removed from the engine. Air bleeds are supplied with their O-rings installed.

Fuel Rail Spacer Fuel Rail Spacer / Insulator
This is simply the plastic spacer that goes under the primary fuel rail for 86-92 where it bolts to the center housing. The rail will not seal correctly to the top of the injectors without the spacer. This is another part that likes to "disappear" during engine work.
