3 – prep the DW300 by installing the fuel sock and retainer. Start installation of the retainer by pressing it
on with your thumb, then use a 4-5mm deep socket to press it on the rest of the way
4 – measure and cut the supplied hose, then install it onto the assembly inlet. Slide the new hose clamps
on the hose toward the top of the assembly and install the DW200/300 with the supplied isolator on the
bottom of the pump. The supplied electrical connector is for earlier Impreza models that came with a
different pump connector design. The OE connector can be retained
