What does this thing do?

Hi, been on Google a bit, but what is this thing on the left of the engine bay?

The picture is from google, but on about that round thing with pipes going into it.

High pressure fuel pump?

Fuel filter i think you will find

Ah ok, that makes sense with 4 pipes going into it

Is that where the fuel is lifted and then taken to the rail for high pressure?

Seems a bit crude.

100% it's the diesel fuel filter housing (as mentioned)
