Fuel tanks

[barnacle]

Being a Volvo Dealer I have never seen a return line going back to the tank. THey use the same method that todays EFI engines use. THe return is fed back to the incomming fuel supply at the engine. Most of the times it dumps back into the spin on fuel/water sep. filter. This saves the boat builder from running extra lines and they can use standard tanks. I also believe that returns are not allowed by the coast guard. You may want to contact your local volvo dealer and ask them about it.
