How can I tell if my car has a 255 fuel pump?

Since I bought the car it has ran rich and I've sealed a few boost leaks and it's considerably better now especially under boost. My issue now is it's still quite rich from idle to about 3500 and under 12 psi, over that rpm and/or boost it cleans up pretty well. To me seems it may have a 255 and it's over running the fpr. Anyway to know instead of guessing?

The only way I can think of is to look at the physical pump.. I am 99% sure there is no other way. Unless you can ask the previous owner?

Cant ask previous owner.

If I pull the pump how do I identify it?

Look at the fuel pump there should be a serial number. and if it's a walbro Walbro 255lph Fuel Pump (DSM / Evo / WRX & STi) - Modern Automotive Performance
Also I'd suggest you put in a 190lph. What size injectors are you running?

Still on stock injectors. Mid-end of May plan on purchasing some 1000-1250's tho and dsmlink.
