Compressed Natural Gas Leak Test: Notes
WARNING: This page is about a different car, the 2002 Ford Pickup, 2002 Ford Econoline, 2002 Ford Cutaway, and 2002 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
After vehicle has hot-soaked for several hours, a very slight natural gas smell may emanate from within intake manifold and intake air system. This is normal, as fuel injectors leak down from fuel injection supply manifold to intake manifold over several hours. Follow all safety precautions. See FUEL SYSTEM SAFETY PRECAUTIONS and/or CNG/LPG SAFETY PRECAUTIONS article in GENERAL INFORMATION.
