One of my 5500s will not start if you let it sit overnight. If you simply prime the manual pump on top of the fuel filter it starts right up and runs great all day.

Anyone ever see this before. I dont have to crack the bleeder-screw on top either, which seems odd...

Check the WIF sensor and all orings- also don't forget the housing. If all else fails, use a little air pressure in the neck and see if you can "produce" the leak.
