A PV adapter carried on the pedal was a pretty common practice at one time. A time when you topped off your tires at gas station air pumps ( for free! ) and refilled your water bottle ( always singular) from the radiator filling hose while you were there. Of course you did have to listen to the gas station attendant ( unless you live in Oregon or NJ, you might need to look up that term) tell you that your tires would explode if you put in more than 50 psi. But that was less of a hassle than trying to fill tubulars with a Silica frame pump.
