Hi,

Does anyone know the specs of the official sti in-tank fuel pump with rotating chamber/anti surge tank?

There's appears to be 2 available one for 93-03 cars and one for 03<

I read somewhere that the earlier one has a stock fuel pump compared with the uprated 180 L/hr in the latter. Is this correct and if so does the later version fit the earlier cars? (I'm looking for one for a 1999 wrx sti type r btw)

Thanks.
