The thingy to affix my Silca floor pump to the tyre valve (I think it's called an "air chuck"😉 is pissing me off. On short valve stems it has trouble keeping a seal, and on long valve ones it likes to stay really put and needs a hurculean effort to get the damn thing off.
Does anyone know if it's possible to put a more "normal like" locking-lever style pump head onto the end?
