I need to replace the fuel pump for my B6 S4, I want a slight upgrade over stock. I was looking at the Walbro 450 fuel pump and wondering if it would fit the tank with little or no modifications needed. Any information is welcome. No trolling please.

Reason I am looking to upgrade is due to the old pump seeming like it might be on it's way out. PLUS: 2.7t swapped my S4.
