Sorry I didn't see an email, and I just today noticed a little red "visitor message" on the board. Never saw that before, so I don't check that even though I log in every couple of days. Sorry to not get back to you sooner.
Glad to help on anything related to propane. Having workded with the stuff most of my life I can generally help you with what's legal, what you can get away with safely, or the things I may do that are a little "safer" than called for due to things I've seen happen in the field.
I'm officially in the office 10-5 weekdays (eastern) but generally here much later, I always pickup the phone when I'm here late. 330-759-7863.
Hot rod I tried to leave you an email yesterday but I think I screwed it up somehow. I would like to thank you for your kind words, it is nice to have someone appreciate what I am trying to do. I wounder if you could give me a call (503) 879-5519 anytime. I want to talk about LPG and valves, lines and fittings. I live in Oregon and am up until 11 pm. If you get the machine please leave a number and good time to call you. Thanks Kenn
