I couldn't find a thread for it in here already, so lets start one!

Not really much to say other than it's awesome and i highly recommend it.

Like people said in other threads i found, i don't know why you really wouldn't get one as a replacement for the stock one.

they're cool also because of how much smaller they are than the stock ones, except they run better?

Crazy.

I would like to thank 93firestpearl for his help when i was swapping out the stock Pump also.

* Yes, works fine in a stock car.
* I paid $133 for mine at subaruparts.com Walbro GSS341 255lph
* It's fairly easy -- at least in a Wagon. Heard its more of a hassle in the SS due to the seats/trunk in the way of things. Have to carefully get the fuel sender pod out of the small hole in the tank with lots of twisting for clearances, etc.

yeah, in the review section though. but it all works :)

i would say yes it's very good. i feel a huge difference in the driving and acceleration, but i didn't just do a fuel pump :D.

you might as well, especially if you are planning on increasing the boost

BTW,

You want the GSS341 pump not the GSS342 pump.

There's also an adapter kit, 400-791 you can buy with the GSS341 pump that makes it a plug & play affair.

Really? whats the difference between GSS341 pump not the GSS342? Just the position of the inlet/outlet, right?
Mine was plug-n-play. I recall it came with a new filter, and the wires hooked up just fine.

Well Josh is right, you DO want the GSS341 pump. I was mistaken in my earlier posts and thought I got the GSS342. Swapped pumps with the SS today and had a chance to compare the stock vs walbro I had installed a while ago.

Anyways, the GSS341 is a direct replacement:

You can get one right from the Subaru dealer. I did for $100 + tax.

Could a walbro overwhelm the stock injectors if you have 0 mods?

Overwhelm? As in the injector couldn't control is duty cycle? I have my doubts, as many on the board have run the walbro with stockish setups and no problems. How ever, if your injector oring seals are bad, then the increased fuel pressure I suppose could cause some leakage.

Why do you ask?

just wondering if a fuel pump going from so low to 255l would be pumping "to much fuel"

Fuel pressure is regulated just before the injectors. Running the Better pump simply insures sustained pressure at higher than normal Fuel consumption rates (bigger turbo, more boost, bigger injectors etc) there is no risk to running it with stock components. Infact some people on the board have commented on performance gains over the stock unit using stock components

Got mine in the mail today. $95 bucks with the kit from Injectedperformance.com with free shipping. They even included a little die cast Hatchi Roku AE86 drift car. Kind of an unexpected addition to my order. lol. Will install tomorrow but i was curious if people were re-using the gasket that goes around where the unit seals against the gas tank. Iv read several threads but no one has mentioned it so it must not be a big deal to use it again (unless it looks like doo doo of course)but i was just curious.

The rubber gasket is fine to reuse unless you see that it's torn or damaged.

Install went great. A little tricky getting the assembly out of the tank though and the old pig tail didnt want to come out without a fight (good thing i got the adapter kit which had a new one in it.) It is a tiny bit louder which isnt surprising considering how much it flows versus how small it is.

+1 for being painless.

Went around my usual stomping grounds after the install and i felt that it stuttered way less when initially hitting full boost, 15psi @3-3.5k rpm. Which is why i got it in the first place. Definitely need to roll around more to be sure though.
