CIS Injector - New Problem :(

[corylang at dccnet.com (Cory Langford)]

Thanks a mil.  Now for the next problem :)

So I decided to pull the injector seats. Figured if I am there and might as
well replace them.  3 came out easy (the plastic piece on the end are
really cracked and brittle) the 4th came out with out the plastic piece.

I can feel into the head and notice that it is still stuck in the head.

Any idea how to get it out?

I really don't want to pull the head, but if I have to....

TIA

Cory
