yeah i just wanted to give a heads up before that happened to you, when it happened to me the gauge in the car was low and when i looked at the one in the truck on the bottle its was like going down and back up, i was like what the ****, the truck was closed and the bottle was open for like a good minutes or two with a kinda slow leak, was almst empty and i had my head in the truck trying to find out was going on, when i started to get light headed and high i was like im guessing its leaking lololol
