Air (lots!) from fuel filter - where to get filter housing?

Okay so update on this;

Just been to fill the tank, took around £41 to fill from just below a third full.
Took it for a test and still the same problem.
Has the get up and go but seriously struggles when up to speed and just cut out on a uphill section of dual carriage way.

Lots of air in the fuel line also.

Going to try a genuine fuel filter and see if that helps.

Don't know about your engine but I had a similar problem on my aaz, ended up being a bad connection to the stop solenoid on the diesel pump.
