Diesel fuel line

I enclosed this link to a roll of DuBro black Rubber fuel line that is going for a price of $51.00
Someone had posted that this item was discontinued and I guess someone wants to corner a small piece of the market.
That said you can still get your fuel line from the makers of Hayes fuel tanks called Buena N rubber
Someone one this site had posted a want for small diesel fuel line and I had responded that I had access to some. I still have some but never heard from the person .

There also is a yellow colored transparent type of tubing which is also used for gas/diesel. I am guessing that the black rubber tubing is being phased out since it doesn't work very well with today's ethanol-laced gasoline. I have had several problems with my 2 stroke yard equipment (leaf blower, weed whacker, and chain saw) where the black stuff just seems to disentegrate. I have replaced that tubing with the yellow stuff.

Of course with diesels, you shouldn't have to worry since there isn't any ethanol mixed in there, but of course our hobby exists off the tail of the commercial market.

It's called Tygon and it like all plastic tubing gets hard as a rock over a period of time. Actually Dubro black rubber is the same as The tubing used in Kraft hayes tanks and is really called Buea N, spelling might not be right but the thing is you can use it in glow or diesel fuels. Another advantage is that it forms well arounf a fuel nipple getting a good grip without hardening. Only disadvantage is that it is not transparent.

Tower still lists it for $39 for a 50 foot roll. IMO the best fuel line for F2D.

EDIT- I see the Ebay stuff is the small. Tower sells the medium only.

Right pat, it is the small line that's discontinued.

Dennis,

Clear (?vinyl?) tubing available at hardware stores or pet shops works well for gasoline or ether/kerosene fuels.

In pet shops, look for the small aquarium air line tubing. ACE Hardware stores all seem to have a rack of various flexible tubing. You can find a pink gasline tubing about the right size, and some clear tubing like the aquarium airline stuff.

The pink stuff is more expensive, and stiffer. Both will harden within a few weeks in use exposed to the fuels. But either -- the clear particularly -- is enough cheaper that routine maintenance checks will catch problems before they cause trouble.

That hardening was the main problem. They are also a bit less heat tolerant than silicone.

Another possible source is a medical supplies store. IV tubing is, I think, a clear neoprene. Very thin wall. Possibly too small in diameter for anything above half-A. Haven't been able to score any of this locally, so no ideas on durability, etc.

Lou, The clear IV tubing isn't too good for fuel line as it kinks real easy if forced it make any kind of bend. I remember when I could go to the local surgical supply shop and buy the rubber surgical tubing for bladders. Wonder with the drug problem in the country if you would have a problem if you went to buy any today. Not that this stuff is ideal for long term use, I still find silicon tubing to be the most useful product.

I was the guy looking for the small Du-Bro tubing. I need it because it's soft and works great in the fuel shut off on my racing planes. Don't think I'm going to pay $51 for it though.

Walt,
I have some of the stuff but I'll make it easy for you. The very same stuff that Dubro sold is used by Kraft Hayes products, carried by Tower Hobbies or your LHS if they are worthwhile can get you this product. It is Hayes fuel line P/N 249 with a MSRP of $2.49 for 4 foot package. This is the same stuff that they use in their tanks.

Dennis,

Agreed, for GLOW fuel, silicone is about as nice, durable and consistent as anything I've ever used.

But, diesel juice has kerosene and ether in it: Silicone tubing swells like well-boiled tubular pasta when those liquids are put through it. ...probably gasoline in spark blends does the same -- haven't tried it.

The black tubing used in automotive windshield washers is supposed to work.

I beat Isky to it for once. These guys have any kind of tubing you may want and they take plastic!

Eric Clutton "Dr. Diesel" has diesel fuel line that remains flexable. Maybe it's small enough diameter for your application.
