Fillpipe Restrictor: Service and Repair

NOTE
The fillpipe restrictor is an integral part of the [1][2]fuel filler neck and must be serviced as a unit.

REMOVAL
1. Use Rotunda Fuel Storage Tanker 034-00002 or 034-00014 and Fuel Storage Tanker Adapter Hose 034-00012. or equivalents, to siphon the fuel from the fuel tank. Use the Rotunda Fuel Storage Tanker to siphon the fuel from the filler neck hose first. This will drain the fuel to a lower level allowing access to the tank through the vapor separator hose attachment. A check valve is located at the lower end of the [1][2]fuel filler neck and will not allow the hose to pass through to the tank.
2. Raise and support the vehicle.
