If you are experiencing fuel flow problems, there is a simple method to determine if the
problem is in your fuel system or your engine. Connect a six-gallon portable tank to your engine.
If the problem persists, the likely cause is with the engine itself. If the problem goes away, the
source must be in the boat fuel system. One component that should be inspected if a restriction
occurs is the anti-siphon valve. If fuel does not flow properly through this part, it must be cleaned
and/or replaced.
DO NOT
remove the anti-siphon valve and replace with a regular barb.

If your boat is equipped with dual fuel tanks, you will have a manual fuel select valve
installed. This valve allows you to choose from which tank fuel will be consumed. Remember, as
the fuel is consumed and the fuel load redistributes, the performance will be influenced. Select the
tank that allows the best performance for your boat.
