Fuel Filter Part number
Hi, is. there any way I can find part number for fuel filter replacement part.
I tried google that came back with couple of. sites, but they don't have fuel filter. They only have common engine oil filters and air filter, etc.
Any pointer are appreciate.

If you're talking a diesel, then it should be in the engine bay or somewhere where the fuel lines go from the gas thank to the engine bay.

That could be why as my car is W213 E400 4Matics 2017 and 276 engine bi-turbo.
When I access to the workshop level ASSYST PLUS. It said my next service is A4 which, according to this https://autogmt.com/threads/w213-service-numbers.1690/, basically I need to do the following
Engine oil + filter
Air filter
Panoramic sliding roof
Fuel filter
Should I ignore the Fuel Filter for my next service A4 ?

If your fuel filter is inline and access is not difficult, I'd replace it. The justification for in-tank/impossible-to-access filters spec'd for 100K+ miles is that fueling station gas is already filtered, so additional fuel line filtering isn't needed. Of course, this assumes you're not frequently filling your tank from dirty fuel cans, or introducing contaminants in other ways.

I really want to replace it only if I know which one my car has and its part number for it.

You don't have to replace the fuel pump unless it's going bad or you have long crank issues. The strainer is attached to the fuel pump and cannot be replaced on it's own.

Some of the in-tank filters are integral to the fuel pumps, so the entire assembly gets replaced. I guess if the filter is dirty after 100K miles, the pump is nearly toast also. If replacement requires dropping the fuel tank, the replacement gets $$$.

This is the "filter" on the fuel pump i'm talking about:
It's attached to the fuel pump and has to be replaced as a whole unit.
