Did some reading and found someone that used one of these adapters with a simple bicycle floor standing manual pump. As a cyclist, I already have a great floor pump and so this is what I am going to do. Will take a little longer for sure but eliminates the risk or over pressurizing the system and gets the job done for under $10. Thanks again everyone.
