CNG conversion back to gasoline question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Has anyone ever converted a CNG truck over to gasoline? I’m looking at a nice 2500HD that is a factory natural gas truck. But would like to convert it over to gasoline.

I had a 2001 Silverado 1500 that was gas and propane. I removed the propane equipment relatively easy. There were quite a bit of power wires for the propane system tapped into the fuse box. With the help of a wiring diagram, I was able to remove or cut the wires that were part of the propane system. Ran like a champ.

Most of these Silverados with alternative fuels were dual setups, gas and whatever else.if this 2500 you’re looking at is a dual setup, then technically you can just fill up with gasoline and drive it normally. You can leave everything hooked up and just not fill the CNG tank.

I removed the propane stuff just because I wanted to clean up the truck. I could have left it if I wanted to.

Thanks for the info. This truck is 100% CNG. It was never a gasoline truck. No fuel tank, no fuel lines. The build sheet shows it was built for CNG. I can buy it right, because the CNG is a tough sale around here.
