DESCRIPTION:

The 1998 Elantra and Tiburon incorporate an emission control system known as On-board Refueling Vapor Recovery (ORVR). A schematic of the system can be viewed on page EC-9 of the 1998 Elantra Shop Manual.

Some owners may experience difficulty filling their vehicle with gasoline and could experience a premature shut off condition as a result of the sensitivity of some gas pump nozzles. The nozzles at many stations are in the process of being retrofitted or replaced by the nozzle manufacturers. In the meantime, owners should follow directions posted near the fuel dispenser, and/or try filling the vehicle at a different gas station.








In addition, verify the plastic Tee connecting the fill vent valve, liquid vapor separator and two way valve is clear by removing and inspecting the Tee connector (part no. 31065-29980; figures 2 and 3).

If the refueling difficulty condition continues, verify that the Fill Vent Valve (part no. 31155-29981) is open by carefully removing the valve and confirming that the white plastic shut-off plunger moves freely inside its cage (figure 1 and 2).

IMPORTANT
When working with the Fill Vent Valve and associated plumbing, be sure to replace the hoses into the proper hose clips (figure 2) to prevent fuel from getting trapped/puddled in the vapor hose. Insure the return fuel from the liquid-vapor separator has a clear path to drain back to the tank.
