content: Seems like the pump is good and the air chuck is bad...So just replace it with a clamp-on air-chuck #6140A61from McMaster/Carr. Fixes it right up and the air chuckwill prob'ly out last -you- let alone the pump? ;)Update:While fixing bicycle tires the kids tried using it andstepped on the gauge which bent the manifold and thatcaused it to leak at both cylinders. Hadn't figured outa way to repair it at this point. :/Up until then pump and especially the new clamp-on airchuck worked great! No kidding. :)I'm buying another and keeping this one away from myfavorite mocosos. ;)(my first review)Alvin in AZ
