Default Walbro fuel pump decrease fuel economy?

If say you were to put a Walbro fuel pump on a stock WRX, would it effect miles per gallon? Or will it still flow the same due to the injectors regulating fuel?

It's the larger injectors that kill it.

It won't do anything since fuel will only flow as much as the injectors allow. The pump will ensure that there is enough fuel flow to the injectors.

the fuel pump will only give you more reliability, supplying abundant fuel through the fuel rails to the fuel injectors.

Go with a cosmos fuel pump
There will be more fule pumped out of your tank but that is why there is a fuel return line as well.
