BTW I am onto something.. I have a way to reuse the stock filters so the pump doesn't have to be submerged. If you look at the bottom of the stock pump you will notice plastic piece can be removed the stock pump and then used on the walbro one. I have another plastic piece that Walbro sent me but if none of that works I was going to do the same thing you did. Good to see I was on track in my thoughts.
