Do your Al fuel rails have a small diaphragm at the ends? I noticed that the stock plastic ones do have that - I wonder if it is for some sort of pressure regulation.

I kept my stock ones bud did shine them up with Meguairs...

I also have not yet replaced the fuel pressure regulator.

And, BTW - the idiot VW engineers ran the fuel lines right where they will shoot gas on the exhaust system when they fail.

I agree with getting rid of all the plastic (including that coolant tower) -- I just have not done it all yet...
