I'm wondering if the cylinder is mounted correctly OR if you are using a forklift cylinder.
is it freezing-up anywhere?
Also, make sure you open the cylinder valve slowly to not slug the excess-flow valve.
I have three units running on propane and the other two don't have any
problems with the set of tanks I am using...but is there a way to identify the
forklift tanks? I can post pictures of the tanks. I see no freezing up any where. I do slam the valve open so I will try doing that slowly. I got my brake bleeder pump ready for tomorrow. Right now we are using the fuel pump but what about just hooking directly from the vac line going to the fuel pump to the reg valve?
