I bought a 95' f250 a few months ago as a project for myself. I intend to try and get around 500 rwhp out of the 310,000km 7.3L. My plan is to do all the supporting mods first so as not to break anything while pushing it to the Max. I've already got alot of good advice and hints off this forum by reading other posts but haven't come across much talking about fuel system upgrades. The truck already has an AFE Stage 2 intake and a 4" turbo back exhaust and a super chip programer which I will be replacing promptly with a t wild custom chip soon. The next thing I was planning was a upgraded HPOP but I read that the stock fuel bowl is in the way. So now I will do the fuel system first. My question is will a system like the Air Dog II replace my stock system completely and relocate it to the frame rail or is that system just a secondary to feed my existing pump, filter, bowl assembly?
