Stainless steel braided fuel return line
 
Can anyone help me cut the - 6 line and put some fittings on?
This is ridiculous, I have tried cutting the line 6 times and it keeps fraying.
What the fuck man. Cutting with a dremal Using aeroquip line.

Two more cuts. Still fraying.
I will gladly pay a shop or garage to do this for me. I just don't know any shops

did u try wraping the line very tightly with tape first? ive heard of some using electical or even ductape

notveryhappyjack 05-14-13 09:28 PM

Here is what i did.
Wrap one layer of electrical tape tightly. Reverse the direction and wrap 3-4 more layers tightly. Used a 4.5 " angle grinder to cut the stainless line. Unwrap the 3-4 layers while trying not to fray it. Unwrap the last layer. Try to swivel the fitting on to the hose. This is where the line is fraying

I just did 4 fittings on 10an hose, just did 1 layer of electrical tape, cutoff wheel, used scissors to cut any straggling wires.
Instead of peeling the tape off I rolled it off without unwrapping it. when putting the fitting on, spin it like you are threading it on.


If you want to drive to Renton I'll do it with ya.

notveryhappyjack 05-14-13 11:33 PM

I have done 10an before with good results.
I'm going to try this tomorrow and take extra effort.

hornbm 05-14-13 11:33 PM

I used a die grinder (air powered) with a cutting wheel. Wrap with electrical tape first. Flawless cut, not a single strand left.

This is why Aaron I'm converting to "Push On" fittings", no more fraying to worry about and just as strong. (just example below, not the brand I would buy)

Really interesting Lloyd. I'm working with what I got on this one. Moving forward I would like to use that push on style. Here Is what happen, yesterday I went to speedware in redmond & they could/would not help me. After that I went and bought a 4.5" cut off wheel like my buddy mention, still frayed the stainless. Today I called a German auto shop in Bellevue that I have spoken with a few times & they recommended me to visit pirtek in Woodinville who is a hydraulic hose & fitting "specialist" I went in and they did even a worse job at assembly and basically told me the -6 lines would not for the -6 fittings.... Meanwhile I was driving away and noticed a car tuning shop and figured I would stop in and ask for help. I spoke with a gentlemen named Raymond who cut & assembled the fuel line in front of me in 5mins. I was impressed. He runs a place called Garage Autohero
Definitely recommend his service to any of you guys. Liked like he had a bunch of cool project working on & he stopped what he was doing to help me out on such a small project. Respect!

if you are gonna do more of these, i would invest in a set of tools called Kool Tools. makes these fittings easier than a drunken prom queen. hose slides in and sits perfectly in place every time. i did my whole fuel system from tank to engine without shedding any blood from frayed ends. check them out.

hornbm 05-15-13 10:50 PM

Out of pure curiosity, how did he cut the hose?

notveryhappyjack 05-16-13 01:05 PM

Ray wrapped the hose with electric tape & used a pair of sheers. Wire cutters made for cutting these hose. Then he put the fitting in a special set of jaws on the vice. He used a little bit of oil and twisted the hose I to the fitting.

1Seven4Me 05-24-13 02:12 AM

the shears are $20 from speedway motors, and the soft aluminum vise jaws aren't bad cost-wise either. most AN hose ends are a breeze with the right tools... occasionally I have one that fights me still, but most are done in less than 5 minutes... it's all about having the right tools.

This is how I do it. You're going to get a little bit of stainless fray. Just take a small screw driver and poke the stragglers into the fitting sheath.

^ man that looks like a clean cut to me!

RotorMotorDriver 07-03-13 12:30 PM

A good sharp chisel and hammer can work too on the smaller hoses (I have done up to -6). One hard hit and it cuts it right off.

I personally have found that shears and the chisel trick work better with less frayed ends versus a cutoff wheel because instead of the individual strands being "straight" at the ends where they can unwind from each other ("too perfect" of a cut), with shears or the chisel method they have a "bend" at the end from being crushed prior to the cut that helps hold the braid together slightly so the strands don't separate as much. Then again, I could be crazy...
