I have attached a pdf that has a diagram of the parts in a SHURflo pump. "The black part (the crack between the the two pieces) of the pump." really doesn't help much since there are more than two pieces to a pump. You will need to remove the pump, take it apart, and determine the source of the leak. That or replace it.
I recently had a slow leak in the SHURflo pump in my Excella. I replaced it with a new one from the local Camping World
. Looking on their website I see a couple of locations
in the Bay Area. Of course you probably have local RV stores too. Since I live close to the North Little Rock Camping World it was convenient for me.
After replacing it and getting everything dry again, then I located the leak in my old one. Turns out it was in the diaphragm that is part of the Check Valve Assembly, 3 in the drawing, that slides onto the Switch Assembly, 2 in the drawing. At least I assume that it is part of the Check Valve Assembly. In the drawing, the part with the hole in it is exactly between the brackets that show assemblies 2 and 3. I haven't repaired the old pump since I have a new one, so I'm not exactly sure which group it belongs in.
You can look for parts online, the web address is at the top right of the pdf I attached. Just keep in mind that the price of parts quickly approaches the price of a new pump unless you search out the fanciest most optioned new pumps.
One other thing, while you have the pump out, scrub the floor with undiluted laundry bleach straight from the bottle. Scrub it and let it soak a while, no need to rinse. It will remove all those black stains and make the plywood look new. Be sure you have some ventilation, but the fumes really aren't that bad.
