QD32 sump , please tell me what pipe connects to that

Doing an engine swap. Bought a new bare long qd32 via alibarba. Im swapping all the extras from a TD27 onto it, manifolds starter etc.
Now on the rear right hand side of the sump, pointing upwards is a fitting made to accept a flared fitting. The TD27 does not have this and i dont know what should be connected to it and where it goes.
It seems to go right to the bottom of the sump so im thinking its the oil pickup for the oil pump but i have no idea, can anyone help.
Thanks David

Your guess will be as good as our sorry. Patrols never had either of those motors. Jump on Partsouq, find a vehicle with the QD32 in it and look up the parts for it, hopefully you can find your answer that way.
