Audi A3 2004/2005 2.0 FSI Sport.
Had a fuel leak a while ago so i took it back to the garage that i bought it from and they said that they sorted it and seemed ok but now the smell of petrol has come back so i want to replace the fuel rails and fittings.
I have attached a photo of the rails, something doesn't seem right, there's paste all over the rails and there's a nut on both the these rails that go into the housing, i want to know are these nuts needed as i just thought the bolts should go straight through the pipe into the housing? (seems to me that they've done a bodge job)
I'm buying the pipes and bolts from audi but when they sent me the order it came with no nuts? do i need them or not?
