Does Cold Start Injector Use O-ring?
Does the cold start injector use an O-ring? The car is an 87 305 tpi. I did not see one on there when I took it off and I am wondering if there should be one.

Yes, it's supposed to have an o-ring.
Another thing, when you put the injector in make sure it seats flat. The metal the bolt goes through is very soft, the injector will **** to one side and it will bend very easy causing the o-ring to not seat in the hole.
I've had to straighten out that mounting hole a couple of times because the bolt was tightened down without the injector seated properly.

Yes, it should have one. Oil the o ring first so it does not tear when installing the injector. When I reinstalled mine, it snapped into place when I slowly applied more and more pressure.
