Has anyone tried Compressed Natural Gas (CNG) Multi-Fuel Conversion in their Dodge Ram 5.9L Cummins? I'm interested to see what the gearheads think about this? Is it safe? Is it a good idea or not? Why? I'm thinking strickly multi-fuel only so I could always convert back to diesel only if samething changes with the price of CNG. Currently CNG is fairly cheap and I read that it would add about 100 - 125 horse power to the engine. Not sure how much foot pounds of torque, but I think the advantage of multi-fueal over 100% CNG conversion is that multi-fuel does not loose any power and 100% CNG does loose some power (I read 8 - 10 horses). Curious to read your thoughts. If your a certified Cummins tech I would like to know what you think. Even if you have practical experience please let me know. Thanks

CNG engines are very different from Diesels, they only share a similar base format. As a Cummins tech you should know that.

Sorry dude I'm not a Cummins Tech.  I was wanting the opinion from a few Cummins Techs to see what they think.  If you look at the links it will show you what type of system it is.  The multi fuel system uses a fogger type system that enters the CNG after the air filter and before the turbo.  If they're any Cummins Techs that can give me some input I would appreciate it.  Thanks

Foggers aren't multi-fuel, they are supplements. CNG engines require sparkplugs to run.

Pure CNG require sparkplugs to run, but I think he wants a CNG/Diesel hybrid which would not need sparkplugs to run bc of the Diesel.

Correct 444getsitdone.  The system I looked at and spoke to the guy that owns the company Marc DeLuca uses a multi-fuel set-up.  Check out the web sites above and tell me what you think.  Thanks

Thanks 444getsitdone, DeLuca Products will run $1400 without the tanks.  Tanks very depending on what type you go with.  The cheapest tanks I saw were around $800.  I think I can get everything between $2500 to $3000.  The CNG Solutions set up is somewhere between $7000 to $10,000.  The CNG Solutions kit has an injector for every cylinder.  Way too high for my taste.  The last I spoke with Marc Deluca he said they are working on a computerized add on to the mechnical set up that will tell the diesel injectors to spray less (15% to 30%).  The good thing about DeLuca Products set up is you don't have to buy a whole new set up you can either just go with the mechnical set up or added the computerized set up to the mechnical set up.  Hopefully this will help the discussion.  I'm really considering get this set up for my 2005 Dodge Ram 3500 Cummins.  Please let me know what you think.  Thanks
