Fuel Return Line: Description and Operation

FUEL TANK

^ The fuel tank is attached under the floor by two straps.
^ The filler neck is soldered into the tank and contains a restrictor to prevent the entry of leaded fuel nozzles.
^ The tank is vented during filling by an internal baffle inside the filler.
^ The tank sending unit consists of a combination fuel pick-up, filter, fuel gauge sending unit and fuel pump. The sending unit can be removed by removing a cam ring which retains the unit.

FUEL AND VAPOR LINES

CAUTION: The fuel supply, fuel return, and vapor collection lines are all coated welded steel tubing. All of the fuel supply and return line connections, except at the throttle body, are made with O-ring connection seal when it is finger tight, however, if the connection is not tightened to the correct torque the connection will come loose and a fuel leak will occur.
Connections from the sending unit to the evaporative fuel line and from the evaporative line to the canister are made with synthetic rubber hose attached with clamps.

FUEL CAP

^ The fuel cap is a screw on type for all series and incorporates a ratchet action which prevents overtightening. A pressure/vacuum safety relief valve is incorporated into all caps. If a fuel cap requires replacement, only a cap with these same features should be used. Failure to use the correct cap can result in a serious malfunction of the system. Correct replacement caps may be obtained from your dealer.
