The Walbro fuel pump for the Subaru WRX/STI is the staple fuel pump for the performance market. Chances are, if someone's selling a high-volume fuel pump, it's a rebadged Walbro. The GSS342 is capable of flowing 255 liters per hour (LPH), making it unsurpassed for performance, particularly in a turbocharged vehicle like the Subaru WRX & STI. As if this weren't enough, Walbro's WRX & STI specific setup kit makes installation a cinch, as it includes the filter, isolator, and all other necessary hardware for a direct installation.
Fuel pump does not come with install kit, must be purchased separately.
