Does anyone know what type/size o-rings are used on an A6 fuel filter? There are 4 total. I could not find any online. I'm hoping they are the same as the fuel injector o-rings because it looks like I can easily buy these.

 

I guess I should mention I have the 4.2L V8 as I am not should if some of the other engines use a different filter.

Any the filter on the 4.2L has female ports which use banjo fittings. On each side of the banjo you need an o-ring (4 total).

 

Check Audi dealer or ecstuning.com. They both have them.

 

Great ecstuning.com has them! Thanks.
