I have 2x044s, plaz surge and walbro 460 intank but if I had to do it all again now I'd go for one of the KPM 1500hp intank setups. Plug and play, no noise, no smell, no surge. If you are going to run E85 and want it to be reliable you will probably need to upgrade all fuel lines between end of steel lines and rail/reg, an upgraded fuel reg and rail as well, although some people get away without them. Expect to run into issues with E85 and the 044s in the long run too, rated for 500 hours but heard of quite a few goong recently including one of mine (may not be to do with E85 though I'm not sure) My advice is spend the bit extra, go with the KPM intank, you will thank yourself in the future. Glad to see you're on top of engine and box, although aren't there a lot of issues with the drive shafts and rest of driveline in the territories with power? Again not sure on that one, someone will chime in
