Struggling with a fuel smell after a drive?

[steved]

I've posted this a couple other places...

After a year or two of chasing a terrible fuel smell after a drive (like, the next day, and for days afterward), I found a tidbit on the FAST EFI forum about a guy who discovered that Summit Braided hose is vapor permeable, and not really compatible with Ethanol in fuels (it says compatible with gasoline on their site, but not ethanol specifically as compatibility), and that for street fuel, you need to run Teflon.

The summit racing PTFE hose lists "Ethanol" specifically as a compatibility.

I changed mine out, and the smell is gone.

I can take the removed hoses and smell the outside of the braid, and they smell like gas still.

Gasoline doesn't mean pump gas, apparently.

Glad you found the issue, I run Pure (Non Ethanol) gas in all my old cars and Mowers.
