Re: Buying Material for Fuel Lines

Is there a special term for that type of fitting (like Bob posted, and TM carries)? I have looked at the local hardware store and they gave me the nut and sleeve seperately and said they were not aware of one that came as 1 peice.

It is called a compression fitting. They can be one piece or sold separately as a compression fitting nut and ferrule. Either way will work. You want to make sure to leave about 1/8" or so of the tubing extended from the end of the ferrule to get a good seal.
It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

Yeah, I've noticed that you leave a little bit of the tubing extended. So, there isn't a specific term for one that has the sleeve "built in" to breakaway once used?

Not to my knowledge. Maybe it's a compression fitting nut and ferrule assembly, I don't know. It doesn't have to be one piece.

I prefer the 2 piece ones. With the single piece ones the ferule that seals the end has to rotate on the line anytime you remove the line, such as removing the hood, etc. That in my opinion, has more of a tendency to cause leaks
If you are not part of the solution,
you are part of the problem!!!

John, the one piece ones, break apart, when you tighten them, becoming just like the 2 separate pieces. just more convenient to handle, in one piece, during fabrication.

I have an easier time of starting the threaded end to carb or sediment bowl without cross threading with the one piece. Seems to align easier than the two piece ones.

I would be wary of aluminum for the same reason you avoid copper for oil and fuel lines: the material would work harden and crack from the vibrations of mobile equipment.

With ethanol in modern fuels, I would suggest something more corrosion resistant anyway.

I always thought they were supposed to, but have seen some that did not.

What I learned on farmallcub.com today.

Well I didn't use to know what they were called...............but a little quality time with Google and I found FORD NUTS. You can even get Ford Nuts in chrome for that over the top look. :lol:

Inverted flare nut is another possibility. Just not as fun!

Don't throw rocks, but I have successfully used 8mm hyd tube several times. (we throw the stuff away around here when it gets bent) Sometimes comes in 10' lengths.. A little stiffer than brake line, but usable.
