RTF, that's exactly what I was considering. One question:
Is stainless a good idea?
I mean, I always go straight to the stainless section at the local hardware, but in this case I wonder. If something did go wrong, extracting a broken-off stainless bolt is nearly impossible.
My thought was to take one of the old ones out (the easiest one to reach, in hopes on only impacting one or two knuckles this time) and taking it to the hardware store for an exact match. And if it's carbon steel, I might decide to stay with that material, just change to a socket head.
Is the pump housing bronze, or just the cover plate? If so, is SS or carbon steel better?
Oh, and one more thing about Speedseal covers. I don't think there's room to flip mine up and out of the way. It's going to have to come off completely, so the slots in lieu of holes won't help me as much.
