I bought a used tank for my build. The placement of the valves and vent in relation to the "down" arrow seems opposite to me. If I turned it over all the writing and the gauge would be upside down. I went to have it filled last night and at 25 liters it appeared to be full. Some white spray coming from the vent. Gauge only reads 1/4 though? The valve is on the vapor outlet, not the liquid. From YouTube videos most tanks the filler and vent are near the top?
Thoughts?
