On all my LS swaps I used either the Walbro 255 internal or Bosch O44 external fuel pumps. C5 FFR on all my swaps. No extra filters and I've never had an issue. My 98 Wrangler with a LS6/4L60E combo has a 255 Walbro internal with a C5 FFR. I installed it 15 years ago and it's still going strong.
I've never killed a fuel pump or plugged an injector due to trash in the gas.
