Anyone know if this one will fit a top feed rail and is the right type? http://www.ebay.com/itm/Brand-New-S...Parts_Accessories&hash=item35dd1a27d0&vxp=mtr
Didn't even click the link. Dude for injectors, just buy something from a known vendor. Save the heartache. And having to buy propper injectors again later (at a min, assuming you don't destroy your engine).
Edit: aaand I missed the words 'top feed' when I posted, ignore me. And to add to all the above make sure you get the necessary O-rings for fitting the injector or it will leak and be incredibly un-fun. Assuming your car is stock you want side feed 370cc for a TT and 270cc for non-turbo. There are differences between the electrical plugs and fitment of the injectors between early and late model cars and you need to either use the appropriate series injector or use adptors for the plugs and a fitting kit to bolt it into the fuel rail.
These are what you want for a top feed rail. http://injectordynamics.com/injectors/id1000/ Suits BDE and Winfactory..
