Severe oil leak

Hi all
I've done a fair bit of digging through threads and I have been unable to find an answer.
I have a pretty severe oil leak coming from the bottom of my injector pump I think and possibly the vacuum pump.
Does anyone know if the photos I have attached are common spots for an oil leak and if so are they just a seal or an o-ring to fix ?

G’day Aaron Mate, I’ve had issues before also on the little brass washers either side of the Banjo fitting that feeds oil to your vacuum pump. You could try giving it a light nip up/tighten but don’t overdo it and they are cheap and easy enough to buy for full replacement from say Repco in blister packs if you can find the exact ID/OD size in stock.
Best to also thoroughly wash/degrease your engine bay so you can pinpoint exactly where your other mentioned leaks may be too.

EDIT: Zooming in for a snippet picture of your vac oil feed and it certainly looks like the left hand washer has been squished to death/leaning/convex.

if you cant find an oring, you can clean all the contact surfaces with thinners and use high temp silicone
