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.

After removing the `bracket`, the leaking hose is clearly visible. Surprise I have to buy a new center support:

What`s this setup for? Does it have to be like that for some reason?
I can`t figure out the reason why I have all those (6) clamps holding together all those short pieces of hoses; instead of having a single connection with a clamp or two. I might change this when I find the proper 1/2 I.D. DIESEL fuel line sold somewhere..
The hose section that rested on the crossbar deteriorated thanks to chafing on the support bracket, I guess. Luckily I saw it that day letting out a few drops but after 60miles of driving it leaked a very substantial amount, constantly. Slowly leaking when engine was not running, but ~~ a Liter of Diesel in minutes of idling!
Back to my original question: how long can the heater hose stay there safely?
and: why several shorter hoses instead of one connection? Any good use of that? (bleeding, priming, etc)
Isn`t it the spot for a fuel pump on the gassers btw? idk...

If it's really half inch, it is a leftover from the cars gas operated days.
The coolant hose will hold a little better than the undercoat.
the clear hardware store hose with braided reinforcement usually lasts me about 5 years. Iif you find a Parker Hydraulics dealer, the blue fuel/oil pushlock hose seems to hold up well. they will also have a single adapter fitting to replace the hose cluster.

I don`t think the car was white anywhere underneath, before this leak. I need to have the 1/2 hose soon. It`s crazy that Autozone did not have it, or Napa. I met a trucker and he gave me a double thick wall heater hose (1/2 i.d.) that would be used on a garbage truck and I have an airhose to experiment if my first junkfix does not hold up well. It might be ok for a few days?

One more thing I`d like to know. The fuel hose I did buy (too small inner diameter) says something I don`t get.

If the airhose is ether-based polyurethane, it makes an excellent fuel hose, and will last a long long time. Often this type of air hose is a transparent tinted color with visible braiding reinforcement. Mine was a blue tint.

The ether-based polyurethane clear fuel hose (found in motorcycle shops, and trucking equipment shops) is also very good, without the braiding reinforcement.

Holds up well to heat, stays flexible and clear. Very resistant to petro diesel, biodiesel, and (heated) WVO.

I have used it to replace the clear line running from the filter to the IP. IIRC, it was 1/2" size that fit perfectly over the cut off ends of the old clear hose I cut off flush at the ends of the nipples. Impossible to get the old hose off the nipples without scratching up the nipples (which would invite air leaks). Also, this allowed (necessitated?) the use of larger hose clamps, which are easier to create a good seal.

RE: Longevity of your heater hose temp. replacement, who knows? What is the quality of the heater hose? My guess would be at least a few weeks. The hose will start to "sweat" long before it starts dripping good.

Do you have a fuel pump at the tank?

Well, I forgot about this a long time ago but it`s still there without issues.
