Fillpipe Restrictor: Description and Operation

Fill Pipe Restrictor:

NO-LEAD FUEL TANK FILLER TUBE
All catalyst equipped vehicles have a special fuel tank filler tube. The fuel filler opening is smaller in diameter than those used for non-catalyst vehicles to permit entry of only the smaller no-lead fuel nozzles. A deflector is installed in the fuel filler opening. The deflector is opened by the no-lead fuel nozzle.

The fuel filler tube on these models has a one way ball check valve. The valve is designed to prevent fuel back splash which may occur while filling the tank.

A label is attached to instrument panel under fuel gauge that reads UNLEADED FUEL ONLY as a reminder to driver. A similar label is located near fuel tank filler.
