FI RCSB fuel pump
Hey guys, currently building a 2005 with twin turbos, 5.3, heads , cam, tbss intake and TB. I purchased a Holley 255lph with the intentions of tuning on 93 with 50# injectors. Ive decided to go e85. My hp goals are 600+whp, so will obviously have to upgrade the fuel system. I found some 114# injectors which is bringing my next hurdle to the fuel pump. My biggest question is how much work would it be to wire a walbro 450 into this holley 255 assembly? I planned on replacing the pump anyways since its rusting and causing an evap leak out of the top of the tank. Just trying to figure out the most cost effective way to do this. I want to stay away from dual pumps. TIA!
