[C320-list] Yanmar trouble

[dprudden]

Thanks to all for the suggestions.

I started by checking the Racor primary for dirt/water but the fuel looked good....and there was fuel. I next checked for air in the lines. There was some so I bled the lines, added 4 gallons of fuel, tried starting, and after a minute or two of rough idle and stalling, she smoothed out and is running fine (20 minutes at dock then 1] hour round trip for topping off tank). Somehow air got into the fuel line. I definitely had a 1/4 tank left and it was flat calm in the middle of a 9 hour motor across Cape Cod Bay (no wind at all!!)
If I hit a wake, is that enough to slosh the diesel in a 1/4 full tank around enough so a bubble or two of air gets in the line? 

Thanks!!!
