    The small fitting I believe is the relief valve return. As far as which side id which, the left should be inlet and the right outlet. Are you able to turn it by hand? If so you should feel suction or pressure. Does the pump have arrows stamped on it?

    Relief goes back to the tank or back to a "T" on the inlet side. If you do that install a check valve.
