I have been searching for a biodiesel-resistant hose material, something that's more commonly available than Viton. Recently, I ran into some stuff called "fuel injection" hose, a Goodyear product, 5/16" ID (about 7mm). It's reinforced rubber like ordinary fuel hose but contains a hard plastic liner that is intended to withstand the pressure of a (gasoline) fuel injection system. I wonder if it will work for biodiesel?

It's sold by Kragen, which is similar to Schuck's and Checker in other parts of the USA. Expensive, the hose sells for $5 a foot here in Northern California. I'm sure it can be found at a discount on line so I bought a short piece to experiment with. The inside fits Mercedes metal barbs and fuel lines and the outside uses the same clamps that regular fuel hose uses so it's an exact size replacement.

I'll try it on my '87 to replace a piece of ordinary fuel line that's starting to melt from exposure to B100 biodiesel. Anyone tried this stuff? I can't find anything posted, searched "biodiesel hose" and "Goodyear" to no avail.
