Do not use any sealant on the "above the pump seals" -- or either of the two metal tube seals. A tiny smear of grease or vaseline is helpful to get them to slide into position. Install the two tube seals on the tubes then insert the tubes into the pump.
Volvo used to make a thicker head gasket to lower the compression ratio for motors with detonation problems - or the unavailability of premium (not so much of a problem now with 10 percent ethanol added in most locales). The fatter "above the pump" seals are meant to compensate for the head being further from the block deck when the thicker gasket is used. Use the thinner seals unless you know the motor has the thicker head gasket. You will need to lever the pump upward, squashing the two upper seals (I use two phillips screwdrivers in the two lower bolt holes and then catch the upper mounting bolts) to allow the bolt holes to align. I use a little grease smeared on the paper gasket as well. -- Dave
