Fuel System

Fuel System
All 2011 Axis Boats are equipped with Pump-in-tank (PIT) fuel systems. This means the
fuel pump is no longer mounted on the engine and is now located in the fuel tank. There
are many benefits to using Pump-in-Tank; most notably is the prevention of vapor lock
and improved filtration of contaminants.
This is a "High Pressure" fuel system. If you ever smell a strong fuel odor, shut down
immediately and inspect for leaks.
The PIT fuel system is not to be serviced by anyone other
than an Axis Factory Trained and Certified Technician.
!
Special tools and training are required to service this fuel
system.
Do not use fuel containing more than 15% MTBE. Also, fuel containing more than 10%
ethanol or grain alcohol is not recommended. A higher percentage of either of the two
fuel additives can cause damage to the engine and fuel system.
DO NOT mix MTBE and ethanol. Drain your tank, or use up as much of the old fuel as
you can before making the switch to E10. Once done, do not go back to MTBE gas. Also,
drain the tank when storing the boat, and put in additives.
Does the gas you are buying have ethanol or MTBE? By law, roadside stations must put
stickers on pumps designating whether the gas has ethanol and how much. A lot of
marinas do not put up stickers, so ask.
Find out when your fuel provider switched to E10 and how it was done. Old fuel and
water should have been removed and the tanks cleaned to reduce the possibility of the
ethanol loosening up old sludge. If they mixed ethanol with gas, you could be pumping a
potential disaster into your boat.
Mixing the two additives can and will cause damage to the engine and fuel system which
will void all warranties supplied by Axis Wake Research, and Indmar Engine Company.
Refer to the engine owners manual for further information.
