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 referring to a gasoline vehicle there is no a fuel filter. There is a little filter built into the low pressure (gas tank) fuel pump, but that's about it. If you have a 2.0 M274 engine for example, the fuel pump part number is A2134707401 which is the entire unit. Depending on your specific engine, that part number might change.

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.

 

Don't forget about water condensation in fuel especially if you live in a humid climate.

 

How do I know if my car has inline filter or in-tank filter.

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

 

Again - going back to my comment. You do not have a fuel filter. You don't have a traditional external "inline" fuel filter like a diesel does for example. If you're talking about the car in your bio (2016 E400 W213 chassis) then you only have a strainer/small fuel filter on the fuel pump in the gas tank that is located under the rear passenger seat.

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.

 

Thank you.... for this service A4, I will do everything above except fuel filter.

Cheers!

 

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 $$$.

 

You do not need to drop the fuel tank to replace the fuel pump. You need to remove the rear seat and remove the fuel pump from there.

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.
