72 318 Scamp. Low oil pressure 1 minute after startup.

Oh I have mechanical oil pressure gauge so I don't have a oil sending unit. Used the Summit racing mopar primping unit. It worked perfectly.

Zoom in on the oil pickup unit. It has grey silicone rubbed on the outside of the pipe. Maybe it had a fracture or leak in it. Think that I'll replace it and maybe the pump too.

Any brand or part numbers that I should get? I really don't want to pull it out again for the same issue.
