what sprung a leak was the rubber pressure hose that goes from the pump to the steel lines. never leaked a drop in the past, and looks good on the outside (not deteriorated or anything) and is still flexible and whatnot.

anybody have any input on the idea that if air got in the pump hydraulic fluid supply hose (that comes out of the bottom of the reservoir), it could translate into the pump "running dry" for a while, producing some kind of increased pressure that caused the pressure hose to spring those holes?
