will a walbro 255 fp kit from an 05 evo fit my 02 wrx? all i know is that they both use the same fp.

 

I know the pump itself will work but you may need to buy a new kit for your wrx? The kit itself is not that much money so it would probibly be a good investment. Good luck

 

whats in the kit?
the strainer and hose and clamps?

 

Yes, but there is also a wiring harness... my guess is that they wouldn't be the same.

 

yes Walbro's WRX/STi/Forester fuel pump has a specific setup kit as it includes the filter, isolator, and all other necessary hardware for a direct installation. The kit is not required but it is recommended because it includes a new filter hope this helps.
