Carbed, fuel line?

[Nevadasmith]

So I had an outing yesterday, and I had some fuel dilivery issues..I think it was vapor locking between the tank and the fuel pump, though the suction on the fuel pump seams week. We ended up rigging up a Gatorade "axuilry fuel tank" under the hood. It got me home a quart at time. My question is the Napa/Gates green stripe fuel that is ethenol safe, and only 3 months old is rotten, swollen and turned to mush. What fuel line will hold up? I'm running unleaded, with 10% ethanol.

This is what I use. B100 compatible. im currently burning B9 and holding up fine. Lined rubber hose. I would guess its would hold up to ethanol but you should double check.

The stock Nylon line seems to work fine.

For the flex hose sections I use Gates EFI pressure rated "Emissions Barrier" fuel hose, carb'd or not. This stuff runs me locally about $3/foot. It is lined with something that appears to be either polyethylene or Teflon. Every LAPS that I've asked for it in has had it, nothing exotic or difficult to get.
