Default 2015 WRX Fuel Filter?

I have a 15' WRX nearing 72k miles and noticed that the service manual says to replace the fuel filter for the car. I've tried Googling and searching the forums, but I haven't seen much information about people replacing it or not.

I've also called the dealer to see how much they'd charge and got quoted for about $560 just for labor. The service adviser also sounded surprised when I asked and said "Why would you look into having this serviced?"

I'm just looking to see if anyone here has replaced theirs or if it's something that can be ignored until an issue comes up.

Unless somehow the gas stations you go to has very dirty gas, usually it should be fine for the life of the vehicle.
It's in the fuel pump so idk if it's something done routinely.

the only fuel filter i know of is the one at the fuel pump in the fuel tank. its actually pretty easy to do it but make sure you have a near empty tank + depressurize the lines before you do it.

to depressurize the fuel lines you basically start the car with the fuel pump fuse removed and wait about 10-15 mins for the motor to shut itself off.

Is bigger than yours.


You got something weird going on if it takes 10-15 minutes for your engine to die without the fuel pump running.

Here's the deal though - on the newer vehicles the maintenance schedule says to replace the filter (built into the fuel pump module) at 60k intervals, but nobody does it.

I'm not sure why they're saying it's $500+ in labor, unless there's something crazy with those fuel pumps, as I've done a bunch of one way check valve removals under warranty and it only pays like an hour, and that's pulling the pump out then reaching down in the tank and yanking a rubber check valve out.

I installed an aftermarket fuel pump and can confirm that the fuel filter did not seem dirty at all. I swapped the pump around 80k miles. I am not a mechanic but I enjoy fiddling with my car and it took me maybe 20 minutes to get the fuel pump out.
Why the dealer is charging over $500 is ridiculous. But probably the same reason a dealer near me told me my head gasket is leaking (for the 3rd time after they replaced it) and said the warranty is up but they'll give me a discount of $3000 to replace it...oh and by the way my A/C compressor is going out too so I'll be given a discounted price of $2000 for replacement. Yeah...no, they're after your money. I got second and third opinions from trusted family mechanics and they found nothing wrong. No leaky head gasket and frion was just low.
