lpg to cng

[sean conry]

I recently acquired a 2000 suburban with a lpg conversion kit, since new. I am trying to find info regarding what the difference is between cng and lpg, and what would be required to "convert the conversion" to cng and set up a home fill station, etc. I am new to alt fuel and dont have much to draw from. Any info would be appreciated.

There are some sigificant differences.

Call this guy, he owns a shop that does both LPG and CNG work, he can give you an idea of how feasbile it would be.

In the Phoenix area you have Darrel at ALT Fuel Systems in Mesa 480-641-4911, or Kevin at AFV Tech in Phoenix 480-600-5804.
It would be cheaper to start from scratch, since the propane system would need to be pulled out before the natural gas conversion can be added. so you will start out with more labor than a normal conversion. Because of the difference in pressure between the systems I don't believe anything will be interchangeable. Darrel at ALT Fuel Systems may give you some credit for the propane parts since he does a lot of propane repairs.
Give us a call when you are ready for fueling equipment, we take care of everyone in Arizona.

Re: lpg to cng

Sean I'm glade you brought up this topic since I am interested in converting a LPG tractor to CNG. I don't think it will be as difficult as some want to make it sound.
My only experience with converting LPG to natural gas is a Ford industrial six cylinder onan generator. I have run the generator on LPG through the original LPG regulator and I also run it on natural gas from a gas well that I regulate down from 500 psi. on a normal service regulator. I realize that a 1970's ford engine is less complicated than the newer automobiles and that might be the difference. I am not an expert and would like to here from others that have tried the conversion.
I am also a new member making my first reply. I have purchased a FM-2 and am now looking for a vehicle in Texas. I have been montoring every post for about three weeks and am very impressed with the amount of CNG knowledge the members have and their willingness to help.
If anyone has a CNG truck for sale near Texas, I'm interested.

Re: lpg to cng

Welcome to the group, Terry. I have cng and lpg vehicles myself. You may want to watch EBay, search "CNG," as well as watch the "Marketplace" here in cngchat. Keep us posted on the progression of the conversion and the things you learn along the way because, as you pointed out, there's always someone... somewhere, that wants to know as well. Don't forget to post pictures for us.

Re: lpg to cng

None of the components are enterchangable. I have converted some weird stuff trust me on this. I have done LPG to CNG on certain vehicles before but it almost amounts to a full blown conversion anyways. These vehicles that are eligible are few and far between. You would be better off buying a blank canvas, rather than pay to remove the LPG components and then start with your CNG install.

Kevin - kick in here if you think otherwise.
