    I watched a YouTube video on how to change your high pressure fuel filter on a Honda GX. That's exactly how the video said to bleed off the pressure - turn off the valve by the rear wheel, start the engine and let it run till out of gas.

You may need to have an error code reset as I have read somewhere to never run the fuel lines all the way empty.
    This was not the case when I changed the fuel filters on my 07 Civic. The car idled for almost 2 minutes with the valve closed, then ran out. Changed filters, and re-opened the valve, and the car started. Nothing else was needed.. Just my $.02

    Curtis i am very interested in your point of view on what is the possibility of finding a Used Honda GX 2006 and up at this time. Thank you for any response! i am new to this CNG business and any additional info would be wonderful. I am getting this vehicle not only because of the emissions but because i will have a 75 mile round trip drive everyday and i am a very frugal person.

    thanks again

    I just purchased a 20004 HONDA GX that has an auxiliary CNG tank in the trunk. In order to clean out a foul odor in the trunk, I turned a shut off valve located just behind the rear tire on the drivers side. I then proceeded to disconnect the tank from the fuel line and took the tank assembly out of the trunk. When I tried to start the car, it ran for a few seconds, then cut out. I towed the car to a filling station and proceeded to fill the tank, but the gas just ran straight through the open fuel line. Upon further inspection, I think that I shut off the valve to the main tank because it appears that the auxiliary tank is connected by a T fitting directly into the fuel line and there is no shut off valve for the auxiliary tank. My dilemna is 1) Can I cap off the auxiliary tank inlet, then fill up the main tank, 2) Have I done any damage to the CNG system by releasing the pressure and allowing air into the system, 3) The auxiliary tank expired in May 2010, do I need to replace the tank, or can it be reinspected for a few more years?

    Yeah, getting to the LP filter is no piece of cake and I wouldn't want to have to do it myself, but several here have. If you had said the car had been home refueled exclusively I wouldn't be too concerned. Public stations are, for the most part, all oil lubed compressors. Their maintenance is beyond your control. If their desiccant cartridges are old/failed, or the 3rd & 4th stage rings are getting worn, the unit could be passing oil. Some areas of the country have "wet oil" and can have an impact on the filters.

    As you know, working for a Honda dealer requires my advise to err on the side of caution and tell you to follow the factory maintenance schedule. A fouled injector can run $500 and be a real pain. Unless you know all of the factors I mentioned are 100% not an issue... I might suggest you side with caution.

    Hi Curt,

    I'm in Utah and have a fuel filter question regarding a 2006 Civic GX I bought about 6 months ago. It had 42K miles and the previous owner filled it at home with a Phill unit. I fill almost always at newer stations which I assume have oil-less compressors. I just now got around to changing the filters at 48K, which the previous owner never did. The HP filter had absolutely nothing in it. It was dry and as clean as the new replacement filter so I left it in to save the new one for later. With the HP filter being so clean, do I need to worry about even looking at the LP filter right now? If nothing is getting into the HP can anything somehow get past it and contaminate the LP? The LP seems hard to get to and I don't want to pull it out if I don't have to.

    Thanks!

    The Odyssey is not legally able to be converted to cng. There are no EPA approved conversion kits currently available for it, and no known plans to make it available in a cng variant in the foreseeable future. I don't think any other cng models will be available from Honda in the next in the next 3-4 years... sorry to say.

    We would all like to see more options from Honda, as well as other manufacturers, but economics has a roll to play in decisions like this. Demand for cng vehicles has drastically dropped, right along with oil prices, as has always been the case.

    People need to develop longer memories. I expect that oil prices may stay down for a while, but they'll eventually stabilize at about double where they are now. Additional offerings would entice more buyers to cng, buy only high gas prices seem to drive people to make the change.

    Not surprisingly... most wonder why they waited so long to do so.

    Do you know if Honda is planning to offer any additional CNG vehicles - specifically the Odyssey? Is it possible to convert the 2009 Odyssey to CNG by independent converters? Thank you.

    I'd say about 18.7. I have a listing of tanks from SCI, the 210 litre is 17.8, the 230 litre is 19.7, so your capacity is right in the middle.
    Generally you can take the volume in gallons and divide by 3.2. for 3600psi.

    Is there a formula to figure out gge? I have a 2001 van that holds 220.5 liters at 3600 psi. What is the GGE?

    Start with the main list of forums. You'll find one listed just before the Main Forum that says to "Read before posting questions on conversions". Then there's a ton of info, including the question you asked, in the conversions forum. There's also the search tool in the blue line with the calander, members list, etc. Please take a little time and do a bit of reading. If you can't locate the specific info you are searching for... post a specific question, ok? Welcome to the cngchat.
