Barry Naumann uses Lucas Power Steering Stop Leak in his International 7400

I work for the Department of Public Works. One of the Internationals Model 7400 had a leak in the power steering unit. The truck was using eight pints per eight hours, which of course equals one pint per hour. I went to the local parts store that I deal with, on the shelf I had seen a bottle of your power steering fluid stop leak. I asked the parts person at the desk if it works. He said that he never had a complaint about any of your products. I purchased the stop leak over six weeks ago and they never had to put another drop of power steering fluid in the pump again. I verified with the Senoir Mechanic and he said that they never repaired the pump. Thank you!
