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.

Walbro pump and install kit in 08 wrx

, Feb 18, 2010
pump is a real walbro and at a great price. the install kit is completely unnecessary and worthless. dont waste your money on it. just buy the pump. the install wasnt that bad but took grinding of the factory housing to get the pump to fit in the housing. it is just like the legacy gt.
