Fuel Pressure Gauge Kit - PU43506-A
IMPORTANT: The EFI fuel system remains under high
pressure, even when the engine is not running.
Before attempting to service any part of the fuel
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.
