1450 Hydraulic Line Break - Need Advice

[ol'George]

You can Silver solder or braze your broken line, I don't recommend it as it will prolly break again in that location, but will work for a while.
You will not double flair the line because you will be reusing your old fittings and sleeves ( unless you choose to purchase new Hyd. --parker style fittings)
the sleeve takes the place of a double flair in tubing work.
Use an old ball bat in your vice to "pull" the line around to make bends
And I mean pull with both hands, hard!!
If you try to just push the line around diameters you will kink it.
Your inexpensive bender might work, but as mentioned you will not make small factory bends without machined dies in a tubing bender machine.
The tightest bends you can make are about the radius of the big end of a ball bat or your bender.
Do buy a 60-72" length piece of brake line, as you will scrap a few of your first bends.
I guarantee your line will not have factory looking mandrel bends, but long flowing radiuses direct the fluid just as good as tight bends just not as purdy!
Do put your nut on first and then your sleeve, the flair, then try your luck at bending your tubing in that order.
You can straighten the tube back straight if you don't kink it.
A minor kink can be straightened with a hammer but not one that impedes the flow of the fluid.
When your done you will hopefully have something that will work, just not look anything remotely like factory.
When it is all said & done it will not be less expensive than factory used lines.
But you will have satisfaction and learned something.
I bent a lot of lines putting power steering on my 782 and 1650 using the ball bat as a radius.
Guess what? they work just fine.
