Vegetable Oil SVO WVO waste cooking oil as biofuel

[powerstroke73L]

I'm redoing my fill station in the garage and I'd love to find a hose that will stand up to SVO and also stay flexible in the cold. I have a clear PVC hose now that works fine, but once it gets down below 40 or so it damn near freezes solid. I don't think regular old black (Buna-N) rubber hose will work because canola oil destroys it-my sources are a mix of canola, soy, and peanut. Anybody have a good suggestion?

Black rubber hose works fine for me for 5 years with a mix of canola-soy-sunflower-safflower. Mostly canola and it hasn't hurt the hose yet. I think the issue with canola/buna-n is exaggerated or requires conditions I never see. Or maybe since my black rubber is fuel rated hose, it has some protection.

Real world experience beats what I've read on forums-buna-n it is-good thing too because it's a hell of a lot cheaper than viton.
