injector reseal what to use

[dfink]

Yes I know search. I have done that.
When replacing injector seals the kit comes with 3 o-rings 1 fiber ring and 1 plastic cap. What all do you replace. I thought my o-rings would be hard but they aren't so I don't know why they were leaking after being down for a rebuild. But anyhow.
Do I just put on the o-rings and leave the rest.
Do the little plastic caps just pop off and get replaced along with the fiber.
I have seen posts where it says just use the o-ring I am confused.

The fuel injectors are supouse to use the o-rings. If you dissasembly the fuel rail and the fuel injectors, maybe the o-rings are old. You need to buy a new ones and install it lubricating the o-ring with a little engine oil os petrolleum jelly. That would eliminate your problem.
