I do have a suggestion for you on that pump. When you take off the cap, you will see that there is a rubber washer on the built-in dipstick. I highly recommend removing that rubber washer and throwing it in the trash! I went to check mine one day, and that rubber washer slid off and fell down into the reservoir. I tried fishing it out for about an hour with no success. It has since not caused any issues that I can tell but I imagine it’s not a good thing for it to be hanging out down in the bottom of the reservoir😒
