Did you have any trouble at all after replacing the plastic entirely with rubber? Any risk for the rubber ones to clog much faster than the plastic ones?

You have low fuel pressure and it may be caused by the EVAP purge system. First of all, here is a vacuum diagram.
Basically check the hose from the throttle body to N82 purge valve above the airbox. N82 valve aka EVAP purge valve should click away, and you should be able to hear the noise. If it is working fine, then you should check the large vacuum line running from the valve to the rear of the car, and the related hoses per the diagram.
Also the fuel pressure regulator has a vacuum line going into it. Check that hose as well.

You saved a bunch of dollars by doing it yourself --- Our local dealer costs an even $100 per hour and would have used Genuine Audi Replacement Parts instead of generaic vacuum hose - the major difference being the packaging - I estimate you saved about $300 and had a lot of fun cuddling your Audi.
