I have been searching the net for a while and it seems liike it is hard to find much info on the CNG bifuel vehicles. They are a great alternative here in UT because of the cheap prices(.74/gal!! and staying that way for the next 3 years!!!). Anyway, I was looking to upgrade the size of my natural gas tank. Does anyone know where I could get some info on doing this, or info on adding a tank?<!-- google_ad_section_end -->

 

CNG is not at all like propane. It is under such high pressure (3600psi) that the tanks are very expensive. The small CNG tank on a Honda Civic GX is something like $9000 list price.
