Are all fuel rails the same?

[stocious]

After having my injectors cleaned, wich turned out to be in poor condition, my fuel rail after being disturbed seems to have created a pinhole leak where the injector seats into rail, there is a lot of corrosion around that peticular injector,

So can I get any rail, or do the 3B's have a specific rail

Thanks

They are all different so you need a 3B one. PM Andy10v I think he may have one

Thank you!

The 3B in an S2 coupe fuel rail PN is/was 034133681E. This is also the quattro RR's fuel rail and 3B in an Audi 200 fuel rail PN.

The ABY fuel rail PN is 034133681N which is also the ADU fuel rail PN.

I don't know what the difference is other than the 3B used 034906031 injectors which are different than the ABY's (and AAN's) 034906031B fuel injectors. The 3B fuel pressure regulator is also bolt on and external to the fuel rail in comparison to the ABY/ADU fuel pressure regulator which clips into a cup on the fuel rail.

So, I think you need a 3B or RR fuel rail or somehow change both the fuel rail, the injectors, FPR and inlet and/or outlet hoses to ABY standards.

Good luck.

I have my old one, no issues with leaks but it is corroded. I can get pictures tomorrow if you want?

Who did I sell my old one to?
