Never remove an anti-siphon check valve from the fuel
system. The valves are important safety components.
Clean or replace obstructed or sticking valves.
On electronically fuel-injected systems, fuel return lines
have been installed. With electronic fuel-injected en-
gines, the fuel selector valves select both the fuel feed
and fuel return lines simultaneously. The fuel return
lines return the fuel to the tank the fuel was drawn
from, preventing the other tanks from overflowing.
NOTE: Fuel return lines are not used with carbureted
engines.
Each diesel propulsion engine in your boat is plumbed
to the fuel tank located on the same side of the boat as
the engine. The diesel propulsion system uses fuel
supply and return lines. The supply lines feed fuel to
the engine. The return lines transfer fuel not burned by
