CNG conversion back to gasoline question
 
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.

There are several CNG fueling stations in both Kansas City Kansas and Kansas City Missouri.

KCATA didn't have natural gas coaches the last time I worked there but likely the city departments have natural gas cars and trucks since they tend to burn cleaner.

I did a quick web search and came up with this outfit fairly close to Independence.

Well dang, thanks! I searched and only found 3 in the greater KC area.

I still want to swap it to gasoline if I can though

I used to work on a lot of dedicated CNG and bi-fuel CNG/gasoline trucks. The bi-fuels were easy to convert back to straight gasoline obviously, but the dedicated trucks were missing an awful lot of parts to run on gasoline. ECM's were different too. Can it be done, yes, but I don't know if it would be worth it unless the truck was exceptionally clean and you had a parts truck. And a lot of time......

Looks like at least six stations in the KC area but only two on your side of the river.

Thanks for all the reply’s. The seller was super difficult to deal with and told him I wasn’t interested anymore.
