USING CARE WHEN FUELING
MasterCraft boats are equipped with a highly innovative fuel 
system. This system is designed to provide years of trouble-free 
service. The MasterCraft fuel delivery system is based on the latest 
innovations in fuel handling and safety. 
 
The fuel pump system in MasterCraft boats is specifically designed 
for the marine environment and contains a number of added 
safety components. Because of the special nature of the design, 
there are no user-serviceable parts. Any parts in need of service 
or maintenance will need to be addressed by an authorized 
MasterCraft dealer. An authorized MasterCraft dealer is equipped 
with the special tools necessary to disassemble and service the 
fuel capsule and associated parts. Replacement parts must meet 
OEM requirements as specified by MasterCraft.
 
The fuel line in the bilge area that goes from the tank to the engine 
is a special multi-layer armored line covered with a special material 
known as a fire sleeve. The fire sleeve protects the fuel line in the 
unlikely event of a boat fire. The sleeve is orange colored so that the 
fuel line can be easily identified. 
 
Filling the fuel tank for the first time will take much longer than 
subsequent fillings as air is being displaced in the system. For 
all subsequent fuel-fillings, the process will take about the same 
amount of time as it does to fill a land-based vehicle. 
 
During refueling you should reasonably expect to avoid having 
any fuel spit-back or well-back when using an automatic shut-o 
fuel pump nozzle. All land-based gas stations in North America 
are required to use these; some marinas may not. Therefore, we 
recommend that you never leave the fuel fill unattended when fueling. 
 
MasterCraft recommends daily inspection of the bilge for foreign 
materials including possible gas or oil leakage. As part of your daily 
inspection, include a visual check of the orange fire-sleeved fuel 
line. If you see damage to the sleeve or line or in any way suspect 
damage or fuel leakage, DO NOT START THE BOAT! Immediately 
call an authorized MasterCraft servicing dealer and let him or her 
assess the situation. Leaking fuel can cause serious damage to 
the environment and may be a potentially hazardous situation for
