I just replaced the fuel pump and lines in my 2001 FLTCHI. The pump was very load even could here the hum well rideing. Took a ride of about 400 miles seemed to run fine but still load pump. Next day went to start bike and no load hum all sounded normal. Anyone ever had this happen and is there a trick to replaceing a pump like primeing as thats what i thought after it stoped being so load like a pump that was working harder then normal. Any thoughts?> Thanks
