just about to put oil tank /pipes back on.
I have a union nut that screws onto the bottom of the filter & a connecting metal oil pipe that goes through and pushes into the oil hose. Looking at the parts diagram (parts 13 & 14) below it seems it's not intended to any form of extra sealing:

Just wondering is this design is reliable or leaky ? and if leaky any tips on sealing
I've just removed the paint and muck I had on them and the pipe seems to seat ok in the nut
It relies on the taper on the metal pipe mating with the opposite taper on the filter housing. As long as the tapers aren't damaged, it should seal ok.
