Is it just me or do any of you notice when Using the racor filter the o ring never fits? Frustrating cause its too small and will get pinched or cut. Supposedly a great filter but damn o ring. I was thinking about switching to a donaldson P550833.

I've only used Racor for that last 10+ years. I do notice that the O ring doesn't "stick" to the filter but just lays there. If not positioned correctly and not bumped while installation it goes just fine.

As mentioned, it does help to oil them
