them pick up work good that bolt to the main body BUT i have seen them crack at the bolt hole so i do not use the lock washer with them. but loctite and a much thicker and wider washer then they come with to help hold it on and i use a dab of loctite on all the pump bolts and file the pickup tube end round it a bit so it start better and help from driving junk from diging in and making steel when going in the pump body
