At least if this morning's run is any indication. Delivered the boat to
a local marina for a warranty item and expect it back late today or
tomorrow. Trip to the Keys next week is 'on'.

Replaced bulb and all rubber lines from the tank pick-up point, to the
bulb. Replaced both filters (on engine and fuel-water separator). Had a
service company come by and clean out the tank, sludge, stuff, and he
even managed to get that nut-like part I dropped in last week. Due to
its light weight, basically a small aluminum tube, approx 1 inch long,
closed on one end, it was 'possible' it got picked up by the suction and
partially blocked the pick-up tube.

All appears back to normal now.
