I got Autotech internals I plan to install on my 2011. I had seen some other MS3 build videos where folks say they replace a screen in the fuel line return and in-tank pump feed that mounts on the side of the HPFP with a stainless steel screen. Is this recommended? Are there any other parts are O-rings that should be changed - or had as a backup incase of issues - when changing the HPFP internals?
