REMOVAL
1 1
The gasoline in the fuel supply line downstream of the
fuel pump is under high pressure (49 psi [338 kPa]). To
avoid an uncontrolled discharge or spray of gasoline,
always purge the system of high pressure gas before
removing fuel tank. Gasoline is extremely flammable and
highly explosive. Inadequate safety precautions could
result in death or serious injury.
1. Purge fuel line and remove fuel tank. See
TANK.
2. Remove air cleaner cover and backplate. See
CLEANER.
3. See Figure 4-100. On California models, pull EVAP hose
from fitting (3).
