the bearings when out in my pump housing. I order the bearings and take it to a shop for them to replace. They call me back in a day and tell me that they cant save my pump because its the old housing. He said they could put new bearings in it but he couldnt promise it would last 15 mins. He told me that they have updated that pump housing to a different metal and it will also help with the idle noise. What could be the reason why the pump is bad and did they really update the pump housing for issues dur to the old one?
