That inline pump also gets installed in the tank, so you're not getting around that work. You can DIY your own Walbro 450 for a little less than this kit and get more flow with less complexity. I'm not saying this is a bad option, but you can get more for less if you put in a little more work.

Never had an issue using e85 mixes.

i have been using stage 1 for over a year without issues, all the way up to full e85 without a problem on stock turbos

not my recommendation, just experience

that said, i paid $60 for it used and would not spend 200 to buy it new, id just a proper 450 retrofit for that money
