Anyone run AN fuel lines front to back?

Don’t use steel braided rubber. The old hose gets eaten by ethanol fuel. It’s funny I had the same steel braided rubber hose 20+ years in the race car using leaded race gas. With unleaded 6-8 years at best.

The only issue I have ever had with braided lines is with some brands fittings having the anodized coating fade over time when subjected to a lot of engine heat but never any leaks, just use quality fittings and an installation procedure that works.

Or, properly tightening the house brand, China boi shizz breaks it....

-8 AN feed in the wagon with a Corvette regulator kicking -6 AN back to the tank; and a -10 AN feed in the MCSS with -6 AN return (PTFE).

Works fine, just keep it nice and secure so it doesn't chaff against the frame or body.

Had that happen in my old Turbo Buick, it made a mess. I believe that car had a -10 AN feed and -6 AN return.

So, yes. A lot it seems.

I'm thinking about it. Gonna be pulling the body off here in the next week or so and I'll be running the lines before I put it back on.

Running a -8 feed to a Y block with -6 feeding both fuel rails, then a -6 return to the tank.

Here's where I'm at, I have a stainless hard line bent to match the factory bends with -8 ends on it. I had it made by inline tube a long time ago. I figure it will be a miracle if I am able to get it in the car where it's supposed to be. If I cannot get it in I'll cut it in half and flare the ends and hope I can get it in in two pieces. Just got in from the garage and I pulled the 5/16" original line out in one piece. Obviously the new one is much bigger but I'm not giving up yet. I will use ptfe lines at each end which is impervious to any fuels including nitromethane. I really really really do not want to lift the body to install the fuel lines. My plan B is to use a proper flexible hose. Thanks for the help

On my (unfinished) wagon LSX swap I got a bright idea that I was going to save money by using -8 braided line at the tank and -8 braided line at the engine bay. But was going to use ,5inch aluminum line in the Straight runs of the frame rails. But I think even though the aluminum line is way cheaper that the braided stuff , I cost myself a bunch extra in fittings. Still not finished so I might just go -8 feed and -8 return with earls black braided line.

Lets see some pics!!!

Here is a picture of the stock 3/8 feed and the 5/16" return lines removed. I managed to get them out in one piece. I can't find a picture of the prebent 1/2" stainless line as I received it. I didn't even try to install it in one piece. I cut it about 3/4 the way back and flared the end. I was super excited when I was able to get it installed in the car. I have the front tube mocked up in the car. I'm waiting for my -8 unions to show up and I will connect the two. That's the plan anyway

And to think you could have saved a bunch of money and used OEM nylon materials. 🤪

I am going to buy stock in AN fittings and braided hose..
