I have a Yanmar 4JH2E. Curious if anyone knows how much fuel is returned to the tank? (And if anyone answers "all of the excess" I'll hunt you down and wind your furler backwards! )
The reason I'm asking is my boat has two tanks. I run mostly off the bow tank, fuel is returned to the keel tank. Just wondering if I need to be concerned about overflowing the keel tank with the return fuel.
