Angry 04 Sti Fuel Filter Costs Over $550.00

I live in PA & got some of the bad gas that
caused my fuel gauge to not read completely full after a fill up. So having the
service manual handy & after talking to the station owner I decided I'd change the level & sub-level sensors & the fuel filter while I'm in there. Why the hell Subaru put the fuel filter in there is beyond me, put here's the best part! Page FU(STi)-60 shows how to remove the fuel filter by twisting the housing open & then replacing the filter and dropping the the FP assy back in the tank. So I call my local dealer to get part #'s & prices & he says they show the filter but don't have a PN for it. So I get a call back about an hour later & he says they called Subaru & that you have to buy the complete fuel pump assy & can't purchase just the filter like the SSM shows. Now *** is Subaru thinking here!? Any feedback would be great.

BTW, the part #'s I got for the sensors
are:

Sub 85111AC012
Level 42081FE020

FP assy $550.00!

I would check the main fuel filter in the engine bay (that one only cost $30). The "filter" that is in the tank is only for very large debris. It is really just a screen and I can't see it getting clogged. If it was clogged though it would be very easy to clean yourself and reuse.

The one I'm talking about IS the main filter, not the sock that you're talking about.

Could you remove the in tank filter. Then just use the WRX filter in the engine bay.

Where is the fuel filter in the engine bay? Is it even remotely possible to get to without removing a bunch of stuff?

Ashland Marathon made some bad gas that either contained sulfur in high quantities or white lead. I talked to my local master Subaru tech & they've done 25-30 cars already. Some requiring complete cleaning of the fuel tank, replace all filters, injector, intake & combustion chamber cleaning,etc. This has really pissed me off, because Subaru won't cover it under warranty (understandable) and the station owner just submits a claim to some home office & they decide if they will pay for it. One guy actually had engine damage & the bill was over $3000! My car runs OK (just installed my UTEC & made a couple maps up to about 18 psi), I tried a bottle of injector cleaner & am going to wait a few more tanks of gas before going any further. I'm just worried that some junk might dislodge while I'm under high load, cause me to go lean & blow my motor!

The 2.0l WRX has a fuel filter in the engine bay and it's very accessible and inexpensive to replace. The STI does NOT have a fuel filter in the engine bay where you would normally find the fuel filter on the 2.0l WRX. According to the factory anuals the fuel filter on the STi is located in the rear tank assembly.

mazdman, as far as I can ascertain, your Subaru parts guy is telling the truth. Although the 04 STi service manual describes a procedure for inspecting and replacing the STi fuel filter (now part of the fuel pump assembly) the STi parts database doesn't break out any individually orderable parts within the fuel pump assembly. I can't wait until STi owners start hitting that 30K mileage mark.

Here are two avenues to explore. Ask your Subaru parts guy whether there is a separate fuel filter part number for the 2005 STi. Or, ask him to contact Subaru Tech Line.

Maybe he can order a fuel pump assembly, remove the fuel filter and then return the assembly, telling SOA to bill him for the difference.

I just confirmed here in Canada its the same situation as Jon says

FWIW my parts guy says that Subaru always takes a few years to get these sort of things available as up here the fuel filter is now at the 96k (kilometer)service. I know this is of no help but you can always remove the intank filter and use a 02/03WRX engine bay filter setup.

Here's a picture of my Supra pump install. May as well upgrade the fuel pump while your at it.

damn, 300$ for brake pads, 500$ for a fuel filter? I would concider setting up an external fuel filter.

I also notice that the fuel gauge doesnt go up entirely at a full tank. So, my WRX got full F and would take a while to go down, but now the STI doesnt reach the F and drops down quicker. Stupid lead foot

$80 more, Denso quality with no noise and an easy fit. I like first cost last cost. But to each his own.

The filter is the STOCK STI one, also the strainer.
