Re: Fuel line shut off options?
down, in a conventional diesel setup isn't your fuel pump an electric fuel pump? That shuts when you shut the "ignition" key?
I'm thinking that once you cut the ignition, the fuel pump will shut, and unless your engine has gone runaway (which it can do by sucking crankcase oil even if there's no fuel) it will stop as the fuel is no longer pumped.
OTOH if you have a gravity-fed day tank, you'd need a positive way to cut off the fuel from it.
But the solenoid, the valve, the splits...All good in theory but even if they are done robustly and fixed solid to something, they add more failure points. You know, the more plumbing you have, the more leaks you will have.
Could you instead install an access plate, so you could reach the manual shut-off valve from abovedeck, or another angle?
