Anyone have any experience with PTFE Fuel Lines to run ethanol on 11th gen trucks? I have a 450 Walbro Pump and 95lb injectors. I want to make it a return style system and I'm thinking -8an for the main hose and -6an for the return. but not sure how much length would be needed or what brand to buy for both the line and the regulator. I've read that a cheap line can make your truck reek the smell of gas/ethanol. also what fittings should be used since I'm keeping the stock fuel rails for now.

 

Or should I purchase the BBK Rails for the 3vs?
