I usually keep a few filters on hand and decided to change my fuel filter since I had my truck on my hoist to replace the front PS wheel bearing. Had several WIX 33910s and a couple of WIX 33960s (the newer plastic housing units that replaced the 33910) sitting on my shelf. I remember reading somewhere that the 33960 had a poor inner seal and could allow large particles to get sucked into the CP3, anybody have any experience with that? I notice that the 33910 is still being sold. IIRC, it is made by Baldwin. Anybody know which is the better filter?
