I installed this on my 2005 Legacy GT.
I decided to grab a DeatschWerks DW300C fuel pump with the install kit since i'll be running E85.
Didnt see a write up on it yet, figured I'd do one.
SOOOO many pictures.
First, go to your favorite parts dealer. I've been nothing but happy with IP&T(and parts show up fast because they're local)...shameless plug
Then open the box after it gets delivered.
Should look like this.
Next, make sure your tank is just about as low as possible for little to no mess.
Pull out the fuel pump fuse, run the car out of gas to relieve the pressure from the lines.
Remove the rear seat.
On the passenger side, move the insulation out of the way.
Remove the 4 Phillips head screws from the black access panel.
Remove the access panel.
If you have driven through the desert like me, it'll look like this.
If you*have*driven through the desert, you have a bit more time and effort involved. Clean off the fuel pump canister as best you can before going any further.
Unplug the wire harness.
Pull off the 3 hoses.
Next, remove the 8mm nuts(8 of them) holding the canister/pump in the tank.
Pull out the metal retaining ring.
Pull the whole canister out of the tank. I actually managed to keep all of the gas in the tank and the pump housing. Held it over the tank for a minute, then took it out of the car when it stopped dripping.
I covered the tank so no debris wouldn't fall in while swapping the pumps.
Then, you set your fuel pump canister on your "bench"(a truck tailgate in my case". I used cardboard to help soak up left over gas.
Next, knock it over so that the majority of gas sitting in it goes everywhere. Finish dumping out the rest in a bucket.
After all of that mess is over, Remove these two wire plugs.
Next, pop off these 4 clips that hold the cup to the bottom of the pump assembly, and slide it off.
Look at all the crap sitting in the bottom. and how much is stuck to the sock. Clean it out.
Pull the hoses off the bottom near the sock filter.
Now, compress the springs and remove the C-clip.
Separate the top and bottom.
Unplug the wire harness from the fuel pump.
Be patient and get crafty with two flat head screwdrivers to free the pump from the housings angry clutches...unclip one side, and then the other.
