I have an 84 FXR. It has not run in about 5 months. I replaced the oil tank. I fired it up yesterday and the oil light remains on. Disconnected the idiot light and put a gauge on and still no oil pressure. Checked the routing of oil lines and all looks good. The tank seems to be filling up. I have only run it for a few seconds as the prospect of no oil pressure is terrifying. I am thinking the bypass valve or check valve in the pump has a problem. Can I replace this without removing the pump? If so does it come out with a magnet? Any help/advice would be greatly appreciated!!!!!!!!
