Need info.for this part.

I know this is a regulator..What I don't know is any of the specs. on it.From what I can tell it's made by "Gas-Flo" model#GR-618 but nothing comes up on the internet for it.Can someone let me know where to buy one,or a replacement for it? Thanks in advance.Oh yeah...This is on the street side of the cat.

I have one of these in my Cat. I think it is a pressure regulator to reduce from full pressure down to 16 PSi. Have a look here

Thank you very much Sean that's it. I dug all over and could not come up with anything.

It's a high pressure regulator at a lp tank on the street side of the cat Rich.
