Did you put the right ones in? Did you twist them in and cut the Orings? Did you but them from FIC?

Welcome to the forum one post is enough.

Looks like their website is being redone but call Jon and tell him I sent you from the forum.

Had almost the same thing happen to me...ordered a set off Ebay and half of them were bad. Went with a set from FIC and never looked back.

Lesson learned.

The web site is telling you that the same injector is good for all those years.....think not.
