It had the motor replaced with the current STI setup only 35,000 kms ago..... then again they may have used the old pump. The car has about 140,000 kms.

Any suggestions where to source a new one? It is an '03 WRX but with the engine change it may need a different pump. I will check for any markings and numbers tonight.
