If you do remove the pulley, please consider an A-B-A. We are exceedingly fond of them here, but I am not sure many of us have actually tested it. I forgot to and removed the pump and lines, so it is really late for me to try A-B-A testing. If you look at
Power steering delete - EcoModder, only three members gave test data, so if you take this step, please add it to the table!
