Walbro 255

[boostedtsi0069]

Hi well i posted a problem about too much gas and got several replies one which could be the fuel pump. First off i wanna thanks those who helped me, well i took out the fuel pump and it said walbro and had the "w" symbol. Now what i want to know is this a 255, it has several numbers but none say 255 lph and if it is can this be the problem why its throwing too much gas?

If you're running a stock fuel pressure regulator, then you're likely overruning it. And this will atleast casue your idle fuel mixture to be beyond what the ecu can control, perhaps at cruise and light throttle airflows as well.
