Yanmar 2gm20 lift pump, confused

[Spyro]

I have a leak from my fuel lift pump. I've been looking online and the pictures I see don't seem to match up with what I can remember of my pump. As far as I can remember the fuel feed is via a rubber hose onto a spiggot under the pump next to the manual lever. There are 2 fuel pipes with banjo fittings on the top one going to the secondry filter. where is the other going? The pics I've seen online don't appear to have the spiggot underneath where my fuel feed is. I'm sure it will be obvious when I can see it but I'm not at the boat now. Can any one enlighten me?

The workshop manual i have just shows a conventional type of diaphragm pump.

Mechanical gubbins below the diaphragm. Suction and delivery connections on the top.

There is a plastic water drain pipe adjacent to the pump but the in/out connections are the banjos fore and aft. If the pump is leaking beware of the engine oil level rising - I have heard reports of engines running away fuelled by leakage to the sump.
