Our Yanmar installation has an electric pump to draw fuel up from the
tank. Would a bypass switch to activate this pump make bleeding

===================================

That's a fairly commom practice on larger power boat diesels. It
makes filter changes a lot easier and removes uncertainty about the
ability to get started again. My setup uses a Walbro 6802 fuel pump
with a switch and a couple of small bypass valves on each engine. I
have a third Walbro that can be valved to bypass the backup generator,
thus serving as a dockside fuel polishing system by constantly
circulating fuel through the Racor filters.
