I'll do my best to explain this.....
Three fuel tanks two side tanks of 125 gallons each & one "saddle tank(lowest tank over the keel)" of 30 gallons. When I bought the boat the valves were such that each engine drew off of the side tank closest to it and the saddle tank was shut off.
When I filled the boat with diesel, I filled the saddle tank so full that there was diesel in the vent line. So I opened the valve to the saddle tank, shut off the side tanks and went for a little run. I got the fuel level low enough that there is no longer fuel in the vent line. There are valves on the bottom of the tank, presumable to equalize fuel levels but they don't seem to equalize anything when open, I would image the line is clogged.
So the question is: Assuming I leave the saddle open & open the side thanks, what happens when the saddle tank runs out of fuel? Will it send air bubbles into the system and shut me down or will it automatically pull from the side tanks?
