system, the pressure must be relieved. The pressure
adapter has an integrated relief valve. Connect to the
test valve and release the pressure.

WARNING
* Gasoline is extremely flammable and explosive
under certain conditions.
* EFI components are under high pressure. Verify
system pressure has been relieved before
disassembly.
* Never drain the fuel system when the engine is hot.
Severe burns may result .
* Do not overfill the tank. The tank is at full capacity
when the fuel reaches the bottom of the filler neck.
Leave room for expansion of fuel.
* Never start the engine or let it run in an enclosed
area. Gasoline powered engine exhaust fumes are
poisonous and can cause loss of consciousness and
death in a short time.
* Do not smoke or allow open flames or sparks in or
near the area where refueling is performed or where
gasoline is stored.
* If you get gasoline in your eyes or if you should
swallow gasoline, seek medical attention immediately.
* If you spill gasoline on your skin or clothing,
immediately wash with soap and water and change
clothing.
* Always stop the engine and refuel outdoors or in a
well ventilated area.
