I was doing a CNG cylinder inspection on one of our members car here a couple of days ago. There appeared to be some damage that I thought at the time I would have to fail the cylinder. Being a SCI cylinder I called the company and spoke to Patrick. I told them about the damage and asked them if the customer could bring the car down for them to take a second look.
Well I figuered this was a good chance for me to go down there. Well it turns out its not damage and just the filler material at the end of the cylinder is just set in a bit. They said its safe and ok to operate.

Now the good news! They said they are working with an Automaker on a vehicle that will be CNG powered! They would not say which one but did go as far as revealing its a US automaker! I hope its GM!
