At least it was a quick find, the fuel filter is a piece of cake to do really and easily tested, blow hard lol
My e46 fuel pump lasted just 115000, not sure if it is a hugely common issue. I see several e46's a week and haven't done many tbh. Just a luck of the draw thing I think.
Since winter is coming you mine as well consider when the last time you did other things, like plugs, look for the common vac leak in the elbow and what not.
