This fuel pump upgrade is the best bang for your buck when it comes to fueling solution. This pump utilized a genuine walbro 450-00274... highest flowing walbro 450 comparing to the competitors! Great for ethanol
used core is a cheaper option and still will perform 100%, i will rebuild a used core into a stage 2
new core is a more expensive option but i will go to the dealership buy a new core and rebuild that into stage 2 (looks more presentable)
