A3 sportback fuel filter housings

[Darius]

Hey,
just wanted to ask if anyone knows if there is any difference between UFI fuel filter housings. They all look identical and the only difference I see is the letter at the end of part number. Maybe hoses connects to them differently or insides of the cap is different?. Like 3C0127400A, 3C0127400B, 3C0127400C, Are they interchangeable?
Thanks

LOL.
I have no idea!!!
I’d hazard a guess (and it is only a guess mind) that they are interchangeable as the different letters at the end of the part number are just revisions to one certain part.....i.e they are basically the same .
I’ve only ever come across 1 type of UFI filter housing which strangely enough is common to my 2007 model A3 and my nieces 2011 model A3.....so it was fitted for several years to my knowledge .....

Thanks! I went on and tried (changed ruined housing with letter C to one with letter A) and the car runs so I guess that's ok
