Dear All,

Looking at replacing the LP fuel filter but cant find it's location. Filter I have is as follows:

https://www.buycarparts.co.uk/hengst-filter/13673935

I thought it might be in the fuel tank, but after pulling out the LP pump it's not there. I'm thinking it must be somewhere between the tank and the engine under the car. Does anyone know please? The drawing in the Audi parts manual doent show its location.

Cheers,

Ben

Not rs4, but on my s3 it's under the car, near the back on the driver's side.

I'm a bit lost here, as I took all of the trim off under the car which cover the fuel lines and the low pressure fuel filter is not there.
Took the innards out of the fuel tank, doesnt look like its in there either.

Where is the low pressure fuel filter on RS4 B8.5 please?

Just trying to help here… surely everything from the pump to the fuel regulator is high pressure?
Could a return system be the low pressure?

Hi thanks guys.

He's a link to a drawing showing the low pressure fuel filter. Unfortunately it doesnt show the location.

- My belief is that the low pressure side is everything between the low pressure fuel pump in the fuel tank and the HP pumps. HP side is between HP pump and injectors. <ight be wrong but think that's right.

You have the wrong filter thats why, been there done that, pm me your reg ill send you the part number you need.
