The Walbro fuel pump 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 Mitsubishi. As if this weren't enough, Walbro's specific setup kit makes installation a cinch, as it includes the filter, isolator, and all other necessary hardware for a direct installation.
Evo X requires a special installation kit. The one offered here will not work.
