L455 gear pump replacement

[NHL455]

hi, when replacing the gear pump how do i get a good seal, i have recently replaced it with a silicon type gasket in a tube but seem to have a minor leak? Should i be taking any other steps or should i have some kind of paper or rubber gasket where the pump meets the housing?

A smooth, clean mounting surface and a gasket should do the trick.

There is an oring part number 272310 that goes on flange of the pump
