"The water separator / filter is mounted slightly above the level of the fuel tank." From post # 1.
Man that reminded me of my air leak issue found here http://www.moyermarine.com/forums/showthread.php?t=8205
I believe a small air leak allowed air to collect in the high spot of the system and caused my shutdowns.

Thanks, Marian Claire! I double check all the connections on the water sep / filter.

Talking

If at all feasible I would consider moving the filter/separator to a location lower than the fuel tank. As mentioned earlier this is not an extra burden you want to impose on the pump if it can be avoided.

On Saturday, I motored down the ICW to a resort marina for the weekend. It was a three-hour run and I had no problems at all. The fuel tank was down to 1/2 full at the end. Yesterday morning, I put in five gallons of gas from my can which brought it up almost full. The engine ran fine for two hours and then I had another hard shut down. I had spark, but no fuel flow to the carburetor. I could hear the new fuel pump clicking while the engine was cranking, so I don't think the pump or OPSS was an issue. My water separator / filter is less than a year old, but it could still be the culprit. But I still have not replaced the fuel pickup line in the tank since it looked so good when I took it out, but I might just replace that just to be sure there are no leaks. Anything else I should try?
I'd be looking at pick up tube. Ran for 3 hrs on 1/2 tank (likely 18 or 20 gallon tank)...experienced no problems. Added 5 gallons and headed back...ran for two hours and shut down....so I figure he was somewhere between 1/4 and 1/2 a tank when it shut down. I think the first holes in the tube will be found there.

Did you use teflon tape on the new hose barb?

Fuel blockage

This may sound odd but I had a similar problem with my engine shutting down unexpectedly. When I installed a new pick-up line in my fuel tank it was too close to the bottom of the tank and when the engine was running the tank contracted and the bottom of the tank was against the pick-up tube blocking any passage. I removed the pick-up line, cut the end on a 45 degree angle and solved that problem. Also could you blow compressed air backwards through the line the dislodge any obstructions?

Hope this helps you, Dave.
