It was a fine gasket. Not a cheap knockoff type. Might have been OEM or felpro. If there was a problem, it might have been with my install, or that the pump became warped because i pried it off or something (I had difficulties). Either way, I'm thinking sealant is the way to go. One can see how easy it would be to apply a bead of permatex in the spaghetti-seal groove.
