Fuel filter Mann or Wix

Changed it tonight. idles smooth again as before it was slightly rough.

The Mann filter isn't a cheap filter in a quality way. They make the OEM filter. It's the one you want

I ended up replacing my brand new Bosch fuel filter with Wix filter from Oreillys and problems went away.

I ended up with a Wix 33299 round metal can low pressure strainer with 1/2inch nipples on each end

I decided to change my fuel filter last weekend, and as soon as I started the Jeep up afterwards, a terrible howl was coming from the fuel filter. After doing some research, it turns out that Wix has made a "bad batch" of fuel filters. I can't say if it's specifically this part # or if it affects others as well, but it's a good idea to avoid their fuel filters altogether for a while.
