Anyone running CNG?
Is anyone running there truck on compressed natural gas. Ive seen the have carbs for cng. How do you think these truck would handle cng? at $1.26 you can get about triple the cng for gas. Tell me what you guys know about cng and how you think it would work on the dentsides.

CNG would be a tough sell. You would have to put a lot of miles on your truck to recover your investment. The tank alone is very expensive, not to mention very large. It would approximately $1,000 just for the tank. High pressure lines and fittings also come at a substantial cost.
CNG also has less heat energy than gasoline. It will take more cng to do the same amount of work as gasoline. Read that as fuel economy will go down substantially. Not to mention, even with a large tank, range is still pretty limited. There's also a concern with where to fill your cng tank. You may have someone local, but there's no cng station on every corner. If you take a trip and run low on cng, you would have to drive home on gasoline. Not sure what retrofit system you're looking at, but if you do decide to go down this road, make sure you have bifuel capability so you don't find yourself stranded.

I understand it's about the same,huge expensive tank under pressure, if like heating systems . Not as much power ,so use more fuel. There goes your savings. At least with propane you can find fill up stations. In my area the have two CNG stations about 40 miles from my house. Not sure how that fuel is going to treat the old engines with out some up grades of some sort to the engines. I had a friend that changed over to propane about 20 years ago and ran it about one year and the old engine was gone. I had a brother that used it in a ford 300 industrial engine and it worked well.
