Brake Line Question

I will be ordering new brake lines for my '79 GS550L. I am trying to figure out what fitting I am supposed to be using.

Here is the site I am ordering from. It has the fittings on the bottom of it.

For the front brake lines, I have a 000 and a 002 on both lines.

For the rear, I have a 002 on both brake lines, but I'm not sure what the other fitting is supposed to be. Can anyone confirm what it should be?

Here is the fiche diagram.

I am looking for the two fittings I have marked with a red arrow. Any idea which fittings these are?
 
you do not need the fittings you have arrowed, you need a single brake line that goes directly from the caliper to the master cylinder, measure it carefully.
 
I considered that too, but then I would need to find a way to mount the brake line on the swing arm. Part 3 on the fiche is pretty well secured, and I figured I would just use it again.
 
part number 4 looks like a clamp to hold the brake line. why not just use that on the steel line, or use some proper brake line "P clips" to secure it using the old clamps mounting holes
 
Part number 4 is a clamp to hold that part down, but number 3 is not a rubber brake line. It is a metal tube that runs the length of the swing arm. It's also about 1/4 the diameter of the brake line. The clamp would be too small to hold the actual brake line.

I might do the P clip thing, but there is only one mounting hole to put a screw in. I would feel much more comfortable with 2 P clips on the swing arm, but there is no place to put the second one.

This is why I would like to try to figure out what fitting that is, but I am up for other solutions, provided they look good. So no zip ties or jerry-rigging it.

one P clip will be fine, the brake line wont go anywhere! if you are that concerned, drill and tap another hole for a 2nd P clip.
 
I suppose if I routed it through number 7, then that would act like the second clip anyway.

This is going to be somewhat difficult to measure though..... I guess I'll do that tomorrow.
 
No 7 has a mounting hole and No.4 has 2, so that is 3 mounting holes available for P clips.
measuring the length is the easy part, just use a piece of string, or a bit of old wiring cable, or the best,most obvious way is to measure the original complete brake line from caliper to master cylinder..........
 
I'd ditch the metal tube. Use a one piece like like Agemax suggested. For the front, ditch the splitter too and use a one piece line. These multipiece lines are more prone to leak due to having more than one joint.
 
I agree with Nessism, you don't need that metal tube and just need to replace the entire system with regular brake lines. I did it on my 81 550T and have had no problems since.
