    crazyhorse06,

    I have moved your thread to the CNG Service & Conversion Forum so that others will be able to see your post and answer accordingly.

    From what I know about LPG and CNG systems. They are not interchangeable. The main difference is pressure. CNG operates at much higher pressures than LPG. The tank will have to be replaced with a Certified CNG tank. Regulators will have to be installed to reduce the pressure from 3600 psi to almost 0 psi. I don't know about the injectors, etc. Maybe somebody else knows that end of it.

      First you start by removing all of the LPG components (nothing is interchangable not even the compuvalve) should cost about $800-$1200 in labor. Then step two start your conversion to CNG. Costs may vary.

          In your situation, I would leave it as is. Use LPG in the summer when it is cheap($2.00-2.50/ gallon) and use gasoline in the fall and winter when LPG goes higher than gasoline. LPG at $2.00/ gallon , even with only 95,000 btu per gallon , it's still less than $4.00 gasoline with 125,000 btu.

          The cost to convert to cng may never pay back, unless in the mountain states with cheap cng , or you have your own well.

          Just my $.02 worth.
