marinegrunt 1 Report post Posted July 20, 2017 Are most hot water pressure washers made to where aftermarket parts will fit and work? Reason I ask is I have a Karcher hds 1200 be and I think it needs a new fuel pump. I know on aftermarket pumps they sell them with different ditection on the rotations. Are the shafts all usually the same size? What about how the pump mounts to washer? Mine slides into a round support bracket and is then held in place by a set screw. I'll try and take it off and post some pictures of it later. Maybe someone would be able to tell if it looks like an aftermarket would work. Thanks! Share this post Link to post Share on other sites
