    I have a 2004 silverado v-8 4x4. With the price of fuel going through the roof I have decieded to convert my truck over to CNG. actualy to a bi fuel , gasoline/CNG.
    I want to see if anyone has any information for doing this to a chevy truck.
    so far it apears to me that there are 2 ways of going. using the fuel injection or putting a cheaper kit that puts a injection spacer at the air intake. Any information would be greatly
    I already have 3 tanks and a regulater.

    Thanks guys

    i cant offer any help here but id love to see how this works out for you. theres a few people in my area running cng, but all in smaller cars and they say they only get a round 70-80% of the power they had running gasoline. i guess its an acceptable compromise for big mpgs and a pocket full of green at the end of the week

    Google has alot of information on this topic. You already have the taks and that is the biggest cost. I work for a natural gas company and we use CNG trucks...they dont get very good mileage on CNG and lack power.

    We had a line locator that had a new 2010 Silverado 2500 they converted to CNG and were comparing the savings vs trhe cost to convert etc... I can ask him how that turned out.

    There are quite a few people here doing that, it would help to know what part of the country your in.

    We've got a bunch of threads on here all about CNG, I think we'll need to pull these together into a special forum just for topics like this so people can learn and get everything on topic in one place.

    I think that would be a great idea Steve. It would be nice to have a single place to go to on this website for all your alternative fuel needs. By alternative fuel I don't mean hybrid electric. Also, one thing people need to get straight is that CNG and LPG are totally different. I wouldn't mind being a moderator for that forum either. I am a CSA Certified CNG Fuel System Inspector, I work as a design engineer for a company that builds and tests the kind of tanks for CNG use.

    By all means, I'll put it up next week and please feel free to share some of your knowledge on the subject too.

    Steve - Thanks ahead of time for your work on this. It will be very valuable to have all the info in one spot. I sincerely hope Highmarker stays with the process and shares his knowledge.

    Often times I don't know what knowledge to share - so, it is best that you ask. I have been driving a natural gas vehicle for the past 4 years. I have gained quite a bit of knowledge. I also know quite a few people in the industry, so if I don't know the answer - I know who to ask.

    Highmarker - Thanks for the input and it will be wonderful to have you as a resource. You can bet, I believe, on getting a lot of questions from folks. That is of course after they have searched the thread for answers.
