* Yes, works fine in a stock car.
* I paid $133 for mine at subaruparts.comWalbro 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.

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.
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.
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.
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.
I know this is an old thread, but it's a bump on topic at least.
I ordered the "Walbro GSS341 Fuel Pump" and "Walbro 400-791 Fuel Pump Installation Kit" from Amazon to install into my 1991 Legacy SS to prepare for an autocross that's coming up soon. I'm feeling some stuttering when I use heavy throttle, so I'm hoping this mod will help ensure that fuel delivery is ruled out for that symptom. This is also to prepare for the Rob Tune upgrades I'm installing later this summer, so I need to upgrade for that anyway. I also ordered a Holley Hydramat (PART# 16-111) for this install too. This is an expensive part, but it is amazing. I replaces the fuel pickup sock. If you haven't heard of it before, check out the video from the link below. I put one on my 1997 Legacy after running it at the first autocross. I was getting severe fuel starvation on long right hand turns. I had to run with a damn near full tank to avoid starvation. After the hydramat was in place, I ran that car with lower than an 1/16 tank of gas showing on the gauge. Here's the links. I'll post up anything remarkable after I'm done with the install.
