fuel injector inserts

[Kurt Deschler]

Replace all the o-rings and all the inserts. The insert should be the red
plastic ones. They clip onto the brass holders so they should come out
together. They are most likely to break putting the injector back in.
Total parts should be around $20 with bosch viton holder o-rings. You
should do this job with the engine warm if at all possible since it makes
a huge difference to the hardness of the large injector o-rings (even new
ones). Sears has a 1/2" allen that works good for taking out the inserts.
Clean the brass injector holders with emory paper while they are out.
Lubricate the injector holder o-rings with plenty of gas before attempting
to put them back in. Do not attempt in the cold or you will waste the
holder o-rings and inserts (BTDT).
