I've been out on the EWS website and am considering doing a CNG dual fuel conversion on my 1992 3.0L V6 Hilux 4X4. Has anyone done this already? What are the pitfalls? There are CNG filling stations near my home. I've already checked on the legal issues. Yes, there are state tax credits I can claim as well.

 

i don't know of anyone in the off-road group that has done this. plenty of lpg conversions, though. i've looked into doing a petrol/propane dual-fuel setup, so i have information if you'd like to go that route.

 

pros - Green fuel

cons - temperature sensitive fill rate. Doesn't matter if it's a cascade fill or other, temperature dictates load. Cylinder sizing for your vehicle..definately affects the range. Lower power, less mileage. Difficult to work on the system unless you have a very understanding of pressure fittings and hosing, etc.

With all that said, CNG vehicles are on the road today and working very well. It comes down to choice and fuel type availability. If I was to do a conversion I would go with propane. The pros outweigh the cons.

 

Thanks any information would be welcome. I'm particularly interested if anyone has tried out the EWS Millennium dual fuel system.

How much of a power loss CNG vs. Propane with the v-6 engine? Are there any web sites that compare the two?

one of the guys sent me this diagram of how it's all set up. pretty straight-forward

 

Cool diagram. I also have CNG stations nearby and am wanting to CNG my new 3.4 swap. I think I can get by with a 12GGE tank that should be able to get ~200 miles depending on how much pressure I can fill to. Looks like EWS is the way to go. They definitely have the most info on the web. OP where are you from?
