For the flexible sections of the fuel system I'm using Cohline 2240 which is an FPM/ECO hose and it's even better than the so called 'R9' hose and can withstand 100% Ethanol. It's specified and used by BMW, VW, etc.

For the hard lines I'm using Poly-Vinyl Flouride (PVF) coated dual wall seamless steel fuel pipe. Steel pipes are resistant to corrosion from Ethanol in E10 petrol.

The downside of steel fuel pipes, as we all know, have a tendency to rust from the outside and unfortunately the hand pipe bender I'm using has scratched the coating off in places. So once I'm happy with all the routing and mounting points, I'm going to strip it all off and give the pipes a coat of paint. I also need to de-burr all the ends and blow out any swarf before refitting with the hose clamps.
The installation of the fuel lines has taken longer than anticipated due to the rather torturous route needed to avoid chassis members and the body tub but I'm getting to the end and can start on the brake lines next....
