Here's a link to the rebuild kit. You may not need the guage, but definitely replace the chuck gasket and the leather washer (piston) inside the pump barrel. The new Silca hose is FAR better than the old one, well worth the upgrade. I also at least inspect or if necessary replace the check valve, and replace the O-ring at the base of the barrel (this part is not sold by Silca.)
