Hi Bill,

The plastic thin= g with holes is the injector "diffuser" designed to break up
and better atomize the fuel from the injector.  There should be a= slight
indentation near the top (end with the big hole where the inject= ors sits) on
one side.  This indentation should match a simila= r key in the injector hole
in the block. Take a flash light and peek inside the injector hole in t= he
block.    Insert the plastic injector diffuser su= ch that the two keys line
up - can be a bit tricky to get it to seat pro= perly. I find sticking my
finger down into the end of the diffuser while it is in the block andtwisting it a bit helps.  It may look like its seated, but when= its really
seated its a ways down into the block.

The end with h= ole stays out - so the injector nose can be inserted.  Made
certain you seat this diffuser (if you are going to use it - not essent= ial
but recommended) properly or else when you try to tighten the bolts = which
hold the fuel rail onto the injectors you could break the diffuser= or
damaged the plastic cover (over the injector pintel) on the bottom of t= he
injector.

As best I recall the angled plate of the diffuser sh= ould deflect the stream
of fuel toward the intake port (into the combust= ion chamber), provided you
have the keys lined up.   Then the injector with its "O&= quot; ring is inserted.
The nose of the injector should go into the inje= ctor diffuser but the "O"
ring should rest on its top.

= Hope this helps.

So if you think these things are hard to get in, try getting them out = without breaking.  I was able to get one out OK after some coaxing, bu= t the other got broken in the process.  Guess what they cost.  $5= 8 for upper and lower part...  now that sounds like a proper pric= e for an aircraft part.  ;-(
