My Hunter Legend 40.5 has a CNG tank. Looks like it hasn’t been stamped since 2009. Can’t seem to find anyone to recertify. Haven’t used the system since we bought 2 seasons ago. Any advice?

Sorry I don’t have an answer for you, Sdiring, but I have a similar, related problem. My recently purchased Hunter 35.5 had the original CNG stove removed and I’m wondering if the Eno 2 burner w/ oven will fit in the same space as the old CNG? Anyone know?

From what I hear, the only thing harder than refilling a CNG tank is getting it certified. The tanks are basically SCUBA tanks, so someone who can certify SCUBA tanks may be able to certify it. Or try a welding supply company that sells welding gasses.

Any advice?
Check with one of your local gas suppliers and ask them where they have their tanks re-certified. I learned from them that Seattle has a company and that they re-certified mine for $60. They told me that as long the steel surface remains in good condition; no deep pits, or rust they will last almost forever. Their certification is good for five years. Then another company refilled mine for $30.

I purchased a CNG refill auto adapter on ebay and fill it at out local CNG station. Theres a video on youtube on how to fill. Just be careful to only fill to 2000 psi. The automotive pumps are set to stop at 3000 psi which is to much for bottle.
