  • No tank you

    Just wanted to put this out there. There are a lot of people getting CNG tanks for conversion (right or wrong) and/or getting tanks to add to their current vehicles. As I went to look at some tanks recently I turned down many of them for problems. I know the ones I left behind the guy will just try to sell to someone that just doesn't know what to look for. SO PLEASE EVERYONE BE CAREFUL OUT THERE:

    1. Simple battery test on the electronic valves will tell you if they are working, if not you are looking at about $500 per valve. And no you can not replace with a manual valve the neck size is different.
    2. Watch for flaking of the fiberglass, it means it was left out to the elements too long and never convered
    3. Look for gouges in the tank or cuts in the fiberglass.
    4. Expired tanks. NO,NO,NO....NO! If you buy one I have some expired milk you can drink


    Please add your observations aswell, these are just the common issues I see with used tanks

      Also, if you are going to replace a valve, please contact the tank manufacturer and purchase one that is approved by them. It even says this on the tank:

      "FOR USE ONLY WITH THE MANUFACTURER'S APPROVED PRESSURE RELIEF DEVICES AND VAVLES"

        If you are replacing a GFI (Ford) valve, be careful, some of the GFI valves come WITHOUT the built in PRD -- they are used transit bus applications (with externally mounted multiple PRD's). They look the same except they don't have the PRD plug when you look at valve from the bottom of the body.
