We finally got the Brake and Fuel lines placed.
If I could offer some advice for those that are looking to replace their brake and fuel lines…. Please consider this product and bend your own. It took me about 3 hours to run all four of the lines, the tubing already comes with the double flare and the adapter fittings in place (each of these fittings cost about $5). Another advantage is it is advertised to be 30x more corrosion resistant than regular lines.
So here is how I did mine. The Poly-Armour comes in the following sizes:
Poly-armour size
Witdths:¼, 3/16ths, 3/8ths, 5/16ths, and 6mm.
Lengths, and cost at my local O’Rielly’s:
8" $2.59
12" $2.89
20" $3.49
30" $4.59
40" $5.49
51" $6.89
60" $7.39
72" $9.49
Next I obtained the lengths that I needed to run each line. If someone can correct any error I have made to the diameters of the tubing please let me know, but I have all my lines as follows-fuel and fuel return line in 5/16ths, (Blue) fuel vent line ¼. (blue), Brake lines front 3/16s and rear, ¼ (orange).
Since we are going with a amc 360 we ran the fuel line right down the same way we ran the fuel return line.
Then I measured the old lines that I had and used masking tape to replicate the course of those lines I was missing.
fuel line for
AMC 258 i6 / 4.2l engine- 5/16....138"=72”+60”+8=140”
For V8 same as return line as it runs on the right rail... 113”=51”+60”=111”,$14
Fuel return line is 5/16....113" 51”+60”=111”, $14
vapor line 1/4........ 91"= 51”+41”=92”,$8
Brake line Rear…..1/4.......
103"... 51+51=102”,$14 prop valve to fuel tank crossmember… (the 51” line has a final bend which falls almost exactly on the bend where the brake line bends to go around he shock tower. It is ideal to have the unions in locations where there is no bend, therefore You may want change your line to a 72”, and 30”, giving you 102”.
Brake line Front 3/16ths
38".... 30+8=38”$8 prop valve to left tire
76" .....72+8=”$12 prop valve to rt tire
Here are the totals of the amount of each line
5/16th
51----2
60----2
3/16ths
72-1
30---1
8----2
1/4
41----1
51-----3
Anywhere where you see a plus sign you will need a connector, necessitating (2each)5/16ths to 5/16ths connectors
(2each) ¼ to ¼ connector
(2 each) 3/16ths to 3/16ths
Although the lines can be bent by hand I did use this tool from hf ($7)
Tubing Bender - Save on this Manual Tubing Bender, to make some of the bends, especially those that were close to the end of the lines. While there I picked up this rubber clamp assortment
18 Piece Rubber Insulated Clamp Assortment to temp fasten the lines until I find a more permanent replacement.
This list doesn’t include the lines running from the proportioning valve to the Master Cylinder.
My man wanted the lines painted Orange and blue... I just warned them that too much color makes it look, well a little fruity.
The lines were easy to bend, and it looks like it all fits.
We also fabricated a new proportioning valve plate, and tapped a couple of 5/16 holes to place new studs into the frame for the bracket and the valve.
