Fuel Tubes Purging
WARNING: This page is about a different car, the 1995 Plymouth Voyager and 1995 Dodge Caravan. However, it is still accessible from the selected car via links, so may be relevant.
Use this procedure if servicing fuel system components OTHER THAN fuel cylinders. Close control valve (clockwise) on all fuel cylinders. Open manual shutoff valve. See Fig 1 . Start engine and operate until engine runs out of fuel. Attempt 3 more engine starts. Very slowly loosen both inlet and outlet fuel tube fittings on the pressure regulator until all pressure is relieved.
If servicing check valve or fuel fill receptacle, slowly loosen inlet side of fuel fill tube fitting at check valve. See Figure . Pressurized natural gas may flow from loosened fitting. All fuel tubes are now purged of natural gas between fuel cylinders and engine; fuel system may be opened for repair.
