A pump running dry is never good. You may be OK still if it's not been dry very long but it sounds like you at least need to replace the flexible lines that attach to the accumulators. Before you do, be sure the fittings are tight. You should use a flare wrench on these and be careful not to overtorque them (which may have already happened) or they will strip.

CAUTION: Be SURE you only use the right kind of mineral based oil in the suspension system. You can buy it at any dealer, here at FastLane or at some better parts stores. Use the wrong fluid (like brake fluid) and it will dissolve all your internal seals!
