For the past 6 years I have been working on CNG Conversions and Writing Articles in my CNG Blog http://www.younkincng.com , with the help of my son Jim3 I have started an Open Forum http://www.cngtruth.com to help the Natural Gas Industry to communicate, teach and grow.  I have felt the frustration as I have looked for good information for suppliers, installers and manufacturers of Natural Gas and LPG products.  This industry is the industry of the future, lets push it forward, Jim

    AweSome!! I would like to find out what are the power equivalence and gallon to gallon energy density. What i am getting at is what vehicle range would I expect. Or How could I get a similar range to my old GAS TANK?
    I guess I might need more range since CNG GAS stations likely don’t exist near my location. I guess that’s why we keep the old system in parallel. WAY COOL!

    I have a 94 Cadillac Concours.21mpg $.41@ $3.60/ gallon premium. and an old dodge B-350 9mpg $0.37/ mile @ 3.30/ gal regular gas.

    Does CNG burn more like regular or more like premium GAS?

    How many gallons of tank would replace a gallon of tank volume to get the same driving range in miles or kilometers?

    Thanks,

    GlennNDavis at fuse dotnet

    Also What do the tanks run?

  2. Neil Tunbridge says:

    I’m very interested in owning CNG vehicle. Are there some trucks that are better than others for conversion? I have a friend with a rebuilt Toyota 22R engine, would that work or a larger Chevy Vortec with more fuel tank room. I don’t deal with instructions very well, and was wondering if I could get help with the installation. I have alot of tools and fair amount of skills. I also have a ’95 Dodge diesel pick up with mechanical fuel pump, if it would work well and not cost too much, I would like to convert that also.

    Thank you,

    Neil Tunbridge

    Interested in your CNG kits for a Dodge Ram
    1500 2003 4×4 5.9 litre engine. It has 115,000
    K on it! Very nice truck but have been told by CNG sales in Tulsa, Oklahoma, that it has too high of mileage on it and that it would cost me 7,000$ to do if they could. They said that the kits sold on the Internet are not E P A approved and don’t work well at all. Could you send me some information on your kits through the mail, it is very difficult to find info on these kits. I don’t have 7000$ to spend on one either. Thanks for your time

    • imran says:

      Ibrahim , Which country are you located in ? Your fleet. Did you ever get the conversion done ? I am an American but travelling through Asia. There are the best CNG kits available here which i never saw in USA. And these are most widely used all over asian countries in all kinds of cars and trucks. Reply me if you need assistance.

    Nothing but answers for your questions!

  17. Melensdad says:

    What about BI-FUEL systems, do you sell those? I’d love to pull the big gas tank off the Ford Expedition and replace it with a 10 gallon tank, then install a CNG tank or two under there and have a bi-fuel vehicle that can primarily run on CNG but then switch over to gasoline for long trips when CNG may be hard to find. Do you have such a system?

  18. Tim Sheehan says:

    Jim,
    Now that Romney is going to be President, and he has announced his national energy policy will include use of domestic natural gas. We need pressure on the right people in Washington to build more CNG stations. Like one every 200 miles on every interstate Pipeline in America.

    I know you are thinking “good luck with that” but do you endorse any particular association or CNG group that can lobby for us?

  19. Edward says:

    I have a 2001 Chevy Cavalier it already has a factory CNG tank I was wondering how many gallons of fuel it hold.

  20. Jeff says:

    Jim,
    I took the CNG class in Dixie last April. The teacher there really speaks poorly of fogger systems–saying sequential is the way to go, but I can’t drop nearly $5k into a truck to save $2.50 a gallon.

  21. Dennis Weinhold says:

    Jim……I have an extended body E-350 Ford Conversion Van with a V-10. Do you have a system? I hope to have 3 or more tanks installed. Planning on pulling a mid-sized trailer for a few years.

    • Jim Younkin says:

      I do have systems that would work but tank placement and power loss may be a problem.

      • Dennis Weinhold says:

        This is a 2-valve head design. I will consider upgrading the valves and increasing the compression. I am thinking 2 small tanks would fit at the rear in place of the spare-tire, and two larger (long) tanks would fit between the wheel-wells inside the cabin. That space is covered by a bed and now used for storage.

  22. yasir says:

    do you have cng conversion kits for 2003-2007 lincoln town car and whats the cost

  23. Reed Stokes says:

    I have a 04 Buick Lesabre. Do you have a kit for it?

  24. Nathan Harrington says:

    do you have a Kit for a 2004 oldsmobile alero L4 2.2 ecotech? cost?

  25. Jeff Cold says:

    My daughter has a 1999 Cavalier bi-fuel she bought 6 months ago. She loves it and drives it to work every day. My son went to look at a 2002 Cavalier bi-fuel today, but the CNG wasn’t working. We just didn’t know how much money we could be getting into or we would have bought it. A new IMPCO pressure regulator on eBay is $275. Just the CNG service manual supplement is $200. I wish Haynes would come out with a CNG manual explaining troubleshooting tips, etc. Jim should write one. I can’t afford to drive to Sandy or hunt around for a CNG expert. If I can’t fix it myself, I don’t want it.

  26. Many Thanks for creating YounkinCNG.com | The World’s First (And Best) CNG Blog. CNG Kit Sales, Installation and Info., I actually was seeking for something related and was thankful to come across the information by this specific post.

  27. Mark Sarno says:

    Hi Jim,
    I am thinking of doing a conversion to my fleet of delivery vans. I have 10 Ford E-150 vans with small 8 cly engines. We were given a quote of $8,000 PER TRUCK to convert. I can’t believe that it would be so expensive. What are your thoughts?

    • Jim Younkin says:

      I can do the conversions from $3500 to $6000 depending on the systems, that price is also for here in Utah, I can come there if mt expenses are paid, Jim

    • jim says:

      From what I have read it seems that the cng fuel tanks are the biggest cost. and they have a 20 year life if new. And cars, Trucks dont last any longer any way. jim ward

  28. Arturo says:

    Good morning Mr. Younkin.
    Looks and sounds like you do great work. I have an F150 4.6 from 2002 that I am determined to convert, and wanted some quotes for your service, both in your shop and also in the Bay Area where I live(traveling expenses and lodging added). Please let me know what you think. I’ve researched and looked around to find a price range between $2200-$3000 not including labor. I work on my car and truck but don’t really want to blow up… just kidding.
    Thanks for your time

    • Jim Younkin says:

      An aspirated kit is $600, the labor is $1500 here in Utah, I can come there if you pay the expenses. The tank is $1100. A sequential system is $5100 parts and labor

  29. Roger says:

    Jim, i have a 1998 Honda Civic GX that needs the high pressure regulator replaced. Is there any reason it cannot be converted over to a aftermarket system. If so what will the cost be? Roger

    • Jim Younkin says:

      It would be hard since it is a dedicated system but with enough time and money it could be done

    • jim ward says:

      Can you drive the GX with the bad high pressure regulator? If so How did you find out it was bad? I ask these questions because I have a 2013 civic GX with 13,000 miles and love the car the way it runs and rides. I just like trucks and vans so I’m not crazy about the body style. jim ward

    What is a good spark plug for CNG?

  32. JaY says:

    So many new changes have happened in the CNG world now. Its almost December and now there are only about 5 MAJOR national and international competitors across the US. From my research I’ve notice that the majority of the US is slightly regulated with CNG capability, but the California market has biggest foothold (i.e. infrastructure) yet is the most restricted ( C.A.R.B.) Why is this so? Why can’t they sell bi-fuel?
