2012 GM Express-Savana CNG LPG Tank

The General Motors Express-Savana CNG and LPG were touched on a few early posts, Alternative Fuel Vehicles, Extrication Knowledge at Home Depot, and Ford’s E Series ROUSH CleanTech liquid propane autogas fuel system . I ran across the information below on the different tank configurations that are available the the CNG and LPG vehicles.  Take a quick look and how the tank locations are similar, but still different.

If you want to look at a complete breakdown of the whole LPG system in the GM cutaway van, head over to TECHLINK.   There is almost enough information on that site to put together a great LPG system training class.
