Not sure if this is what you're looking for, but,

I just got through taking it off and resealing it.
It's actually in two pieces, left and right side with
4 stainless screws in each side.
All the notches are cut out according
to the pump design.
PS - All the getto looking adhesive you see was my
failed attempt to temporarily fix a small leak while on
a river trip. Looks tight now.
