i can guarantee you that its the fuel pump because:
1) i know what the fuel pump whine sounds like
2) i can hear it at idle when im parked (that would negate the tires, or any drivetrain noise)
i just dont know if the stock one makes audible noise or not, but if walbro is engraved on it, ill probably just take a look at it
thanks for the help

I swear we did the same exact check on my friends IX last night. His car runs strong for the mods he has done and we wanted to see if it had a pump. Removal and install literally took 20 minutes. The Walbro will have Walbro engraved on it and a serial number. The stock IX pump is completely silver with no engravings on it what so ever. VIII pumps are black I believe. Unfortunately the car didn't have a Walbro

warlboro pumps are pretty loud. your can deffinetly hear them outside of the car and somewhat inside the car. Idk if this is true but i no warlboro makes a high pressure 255 pump now that supossivly flows a lil more then the standard 255 pump and is a lil louder too...maybe you have that.

i recently bought a used IX and im just trying to find out a little more info on it. lately ive been hearing a whine coming from the back of my car. now i KNOW its the fuel pump, what i dont know is if its the walbro or not.
in my searching, all ive seen people say is "if it whines, its the walbro" but that doesnt fully clear it up for me seeing as my old car had a slight whine to the pump and it was completely stock.
so is the stock evo fuel pump COMPLETELY quiet? if it isnt, and i decide to take out the fuel pump to check it out, will the walbro have any markings or serial or model numbers on it?
thanks
