Re: Deisel Engine Day Tank.
Commercial fisherman I have spoken to, say they are a must in the tropics, did not think to ask why. So I guess the answer is the engine is not reliant on a fuel pump feeding the engine during running.
I have been operating in the tropics for 10+ years, with a Perkins 4108. No problems with my system. Gravity feed will not work here.
Fuel pump is engine mounted and driven so it is going to suck.
I had a fuel tank in the bow and the engine fuel pumped sucked it back(20') just fine.
As my diesel mechanic told me "that pump will suck the chrome off a bumper hitch"
Don't over think and over engineer your fuel system. Out here we call it another "stupid cruiser trick". KISS
