FUEL TANK VENT LINE

Sedan model fuel tanks are vented to the atmosphere

at the top right forward edge of the tank. The vent line

is connected by a rubber hose with two clamps one at the

tank and the other at the vent pipe which is secured to the

underbody as shown in Figure 8. A rubber grommet

around the vent pipe acts as a seal to prevent gasoline

fumes from entering the passenger compartment.

It is important to note that the

gas tank is not vented at the cap; therefore, it

is necessary to be assured that the vent line is

free from dirt, etc., and that the gas tank vent

line is open at all times. If gasoline fumes are

detected, the rubber grommet should be checked.

Station wagon and pickup model tanks are vented from

the tank to the filler neck (fig. 9) and use a vented cap.

The vent outlet pipe on the tank is connected to the vent

inlet pipe on the filler neck by a rubber hose. The hose

is secured with two wire clamps.
