So I got a gift certificate for Amazon.com and I was checking out what they had. First, I was suprised to see that there are a few different WRX parts on there for sale. Exhaust, intake, body kits...etc. Well, I am in the process of ramping up for new turbo and I still need to get the fuel pump. I searched for it on Amazon and found out they have a bunch. Problem is that nothing says it is explicitly for the wrx. I know the Walbro 255 pump that works on the subie is the GSS342, but I don't know if the ones they offer on amazon will work. How much different are all the different installation kits. If I purchase this pump off amazon, will I need to get a WRX install kit from somewhere else? http://www.amazon.com/s/ref=nb_ss_g...search-alias=aps&field-keywords=walbro+gss342
