I continually marvel (SMH) at some of the advice people in here ask for without really supplying much useful info to go on leaving us to all guess what the cause of the problem is.
If you've got a fuel leak in the vicinity of the New x 3 filter you just installed then you need to pinpoint if the fuel is actually leaking there or possibly running down a hose to there from somewhere else. I would think that with the vehicle running, using a flashlight would make it real easy to determine the source be it a Hose, Filter, Carb, Regulator or Connection.(Disclaimer: Stay away from the Belts and Fan and Don't cut off your Head or Lose your fingers).
I kinda like a start with 69FBCuda's idea as I recently put on a replacement fuel filter on a rubber fuel line/hose clamp setup and didn't catch that I'd bought one with 5/16" hose nipples vs the 3/8" nipples I previously had which led to a leak...Was a simple catch and fix though!
