If it is running correctly, sell it and buy a gas rig. JMO. You'll be on the road in minutes and if you have to buy a donor rig anyway, you may end up money ahead or even. Plus, your time on earth is limited, why spend it on this?
Thank you for the input.
Probably will part it out rather than convert from CNG to gasoline.
Only problem is steel coolant heater line that runs under the intake manifold, leaks.
Understand this a common problem.
