[BR3W CITY]

I actually run a filter AFTER the pump only. I'm fine with in-tank pumps having strainers or socks, but on externals, I've had nothing but issues with pre-filters.

Some folks buy ones that aren't efi rated, or buy really cheap ones who's screens and cheap bodies don't last very long. Its also important to make sure you're using lines at least -6, preferably -8 if your making power. All that stuff contributes to restrictions. Since these pumps prefer to pump on the head rather than draw (meaning push, not pull), having a restriction on the inlet site is sorta like sucking through a collapsed straw.

I run a 255 and just keep an extra. I've never clogged or burned one out, and my routine fuel filter checks have all come up clean, even after more than 15k mi on my swap.
