My pump is ready to install but I will need 10 mm hose clamps for the ones I removed. Don't really need the clamp on the return hose so wonder why they put one there. These "plastic" flex hoses must be heat pressed onto the pump and pipes.
I did cut that stud off but it was a PITA to cut with a hacksaw blade.
Edit: Forgot to state this pump only needs to compress about a half an inch to seat onto the tank.
