Computerized Engine Controls: Notes
WARNING: This page is about a different car, the 2003 GMC Savana and 2003 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The fuel control system on these engines is separate from the gasoline fuel system and has unique parts. This article only covers removal and installation procedures for CNG components on bi-fuel vehicles. Procedures for systems and components that are the same as gasoline powered models are not included in this article. See REMOVAL & INSTALLATION - CHEVY EXPRESS & SAVANA - GASOLINE article.
