tank compartment door on the curbside ( Figure 53 ).
The second location is on the roadside behind a filler
door in the A/C condenser door.

The fuel tank is equipped with a whistle that stops
when the tank is full. Close filler and latch it securely
after filling.
Do not fill the tank from both necks at once or
have both fill caps open; the tank will over-fill
and overflow.
