Biggest sign that it's fake..
If you plug it in to a 12v power source and it's silent, Walbro is famous for being noisy.
Other signs it's fake:
It's too shiny (ori one not so shiny)
They say one model can fit all cars (Walbro has different model sets for different vehicles)
The wording is too clear (The Walbro and Made in USA - ori one not so clear)
I just had a fake one taken out of my car from the previous owner, will take some pics of it later.
From what I know ori retail set with box etc should be around RM500. The OEM in plain box cheaper a bit around RM400-450.
yeap yeap i second that i was using evo 3 fuel pump before but ever since switch to walbro dam bising lah especially when boosting but it sounds DAMMM GOOOD
