Temporary fuel hose

[RedArrow]

Anyone tried it before?

I was on a camping trip when my car leaked a lot of fuel, started losing lots of diesel due to a retired fuel hose that `melted away` and ruptured. I had no choice there but to use a piece of heater hose I had under my spare tire.

What do you think, for how long can a `standard heater hose` be used as a (bio)diesel fuel hose? I know it will degrade quickly but how fast? I visited many auto parts stores but none of them had the 1/2 ID fuel hose available from the shelf... weekend is here and I have another fishing trip planned, a 250mile drive. I will visit a truck-school bus-ambulance truck repair shop on Monday, they will have it for sure. I guess. If not, I`ll have to order some and redo the whole thing. Pictures show the problem before my SOS fix.
