Wow, this thread might have saved me from a serious issue.
I replaced my Versa filter this evening. It was in very bad shape, dark brown (versus clear) and the fitting ends were very soft and pliable. It was only a matter of time before it cracked, leaking fuel all over. I guess the engine heat must be working on the plastic? According to my records, it had been on for just over two years and 10,000 miles.
I'll definitely replace it annually!
I'll pop a picture of the old one later this evening.
