Which fuel filter?

I have a 2L FI engine. What type of fuel filter do I need. Been looking and there are plastic and glass ones.

 

You can get the propper one's from VW Heritage (plastic) Fuel injection has a much higher fuel pressure.

 

I belive the standard ones on the 2 litre were square plastic ones

 

Can't see them on the website. Only the cylinder ones for carb engines.

 

Is it this one?
