5.4L, CNG to gasoline
 

Have a 2000, 5.4L that is powered with CNG, stock setup.

Want to convert to gasoline powered engine.

Both CNG & Gasoline powered engines have identical stock CR.

Want parts would be required for this conversion?

Most popular conversion is gasoline to CNG.

PCM, Gas tank. Wiring harness, intake manifold, fuel injectors, air intake. A donor truck would be your best bet.

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?

Good luck with it.

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.
