Hello Group. I own a 62 thunderbird with bubbles in the resouiver. I have foe several days turn the stering wheel to the right and to the left going at a crawl speed. Still the bubbles. How to check if its either a bad pump or just a air pocket in the lines. Could I just use a baster to drain the resouir and disconnect the return hose to the resouir or the high side also. Or do I have a bad seal in the pump creating air bubbles. Any help would be appreciated. Larry
