Re: Return diesel fuel to the tank?
The fuel return line to the tank on my Yanmar 3GM30F pumps a lot more fuel than actually goes to the injectors and is burned in the cylinders. If that fuel isn't piped directly to the tank, it will probably back fill into the tank from wherever it 'Tees' into the fuel delivery line. On the Yanmar, there is enough pressure that the hose clamps need to be seated and tightened properly or they will leak a significant amount of fuel.
For the Bounty engineer, not knowing where the fuel return line was plumbed may be excusable. Not knowing that there was a fuel return line means he was incompetent.
