Re: Need help now with O-rings

The old UIM did not have a spring and only 1 O-ring on the pcv.
Now in regards to the injector O-rings, do the injector pull out of the fuel rail? I'm assuming they do and one set of rings go up top and the other set on the bottom. I have pulled gently but can't remove an injector from the rail.
Thanks
See link below for PCV valve guide. Only one small black o-ring goes on the PCV valve. The big orange o-ring seals the UIM opening for the PCV valve and MAP sensor retainer. The spring is for the MAP sensor retainer that locks down over the PCV valve.

Do you think the other o-rings are for the 90 degree plastic elbow. Did the new elbow come with o-rings? The kits have o-rings for the elbow anticipating it will be OK and re-used.

On the fuel injectors, yes they will pull off the rail. Pull harder. You will have upper and lower fuel injector o-rings. Make sure they match.

BTW - The u shaped retainer/clip to each fuel injector at the rail must be removed first before pulling each out.

Good luck!
