fuel return hose on EFI yamaha

[PercyMH]

I have twin yamaha's model SX150TXRY and LX150TXRY.Can anyone tell me if this model has the return fuel hose back to the fuel tank? The boat is out of state, so, I can't walk out and take look and I've never thought about it before, but, I understand that some EFI engines do have this. Also, what is the purpose of the return hose?thanks

no fuel return to the hull tank on that model. some I/O and stern drive EFI and some desiel engines use it. its just a method to return excess fuel from the fuel rail to the fuel system.

thanks for the help. I am planning to install a Navman 3000 and needed to be sure it would work.
