That drain Filter you are talking about is an OEM piece for original TT cars, its a basic drain hose directly into sub-tank, I guess you dont work on real TT cars that often.

No 12v mod needed???
I have an single a turbo swapped Aristo and looking to upgrade the pump, but people are saying the walbro 450 should be wired to a relay and have 12v constant

Im on a jdm tt supra, wondering if 1x450lph will work with the oem wiring or I need to do a 12v mod relay

Did you have to modify any fuel wiring stuff such as a relay?
