The Walbro 255 liter per-hour 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. Walbro's GSS342 fule pump is capable of flowing 255 liters per hour (lph), making it unsurpassed for performance, particularly in a turbocharged vehicle. As if this weren't enough, Walbro's setup kit makes installation a cinch, as it includes the filter, isolator, and all other necessary hardware for a direct installation. While an installation kit is not required, we recommend it because it includes a new filter.
