[wrong generation]

97 3.8 v6 on the fuel injectors do they have an O-ring on the top of the injector or is the O-ring in the fuel rail it self ??

figured id ask before trying to remove somthing from the fuel rail that isnt suposed to be removed and kinda need to know this asap.

[Slow-V6]

The o rings should be on the injectors.

Injectors.

Both, on top of injector, and down at the bottom.

The o-ring is on the injector, sometimes they get stuck in the fuel rail.
