Thread: Followed Me Home II

Tweet

I've been doing some looking, and found a couple of auto magazine tech articles on upgrading fuel lines due to ethanol blends, E85 and pure ethanol fuels eroding lines, and losing fuel due to vapors permeating rubber and neoprene lined hoses, like braided SS. The 3/8" aluminum line that I have is only ~0.025" thick and soft. I think it would be OK, and my first thought was to just use it and let the next guy replace it when the time comes, but that's not the way I like to do things. Steel would be better, but over time it's subject to internal corrosion too. It looks to me like the way to go is a PTFE style hose, like Earl's Vapor Guard. It's a multi-layer hose that blocks vapors and is impervious to ethanol's corrosive tendencies. Headed out to the barn to measure. Looks like the BBT will be back again, maybe tomorrow!

Thanks for the comments!

I re-plumbed everything with PTFE hose when I converted the coupe to fuel injection a few years ago.
