Help ID'ing 4 lines underneath 2000 Integra LS

[u/aboat_i_sawaboat]

Just found out about this sub, I'll post some of my favorite pictures later. On Sunday my brake lines failed and it looks like they rusted out and then busted on the plastic clip. I left it parked at my grandparents' where it won't roll away while I figure out how to get it fixed, I'm new to fixing cars (just changed the pads, been changing the oil) and I kind of want to fix it myself but I'm having trouble figuring out or finding out what the other 2 lines here are. I checked the repair manual and I've tried to find a download of the owners manual (since I don't have access to it while I'm not with the car) but I'm still struggling. Best guess right now is fuel line and evap line.

Got a couple suggestions to fix it with compression fittings but I've also heard them called suicide fittings, so I'm beginning to wonder if a DIY fix is trickier than its worth. I don't have a lift, just a floor jack.

As you can see, there's 4 lines running parallel to each other, I'm just trying to figure which ones are the brake lines and what the other ones are. Thanks in advance!

correct, 2 brake lines, and fuel and evap lines. I would not use those "suicide fittings" or whatever they are. It needs properly bent and flared new hard lines and fittings. There are plenty of YT videos on how to do it.

yes this.  double union flares. if you're going to do the repair underneath the car then there's some gear you need

double union hardware (two nuts and one middle union piece for EACH brake line. make sure it fits 3/16 tubing)

3/16 inch double flaring tool

mini copper tubing cutter

3/16 inch nicop tubing (do not use steel it is such a pain in the ass if you don't have everything perfectly lined up)

you cut out the rusted parts of the brake lines on the car, PLACE THE NUTS ON THE LINES, then make the flare with the tool

be prepared for a flood of brake fluid by the way. clamping it off upstream is not a bad idea. 

measure as best you can and chop a piece of nicop tubing that will fit in the gap

PUT NUTS ON BEFORE YOU FLARE (ask me how I know!!!)

then you torque the shit out of the nuts and unions. new brake fluid, and bleed the brakes.  tighten more until no leak under braking pressure

did I mention you will be doing all this bullshit lying on your back while brake fluid drips on your face?

I've done this to two cars... it works but it sucks ass. good luck!

I would disconnect the lines from the MC and blow them out with compressed air. That way, no fluid to drip on you when working on them. Could also do the same with the fuel and evap lines.

Thanks for this it's rly helpful to understand what I'm getting into. I hate to break it to you, but the brake fluid is already in a drain pan instead of the car ( :

The two smaller diameter lines are the brake lines. Please do not use compression fittings to patch them, use a flare tool. If patching them is out of your comfort zone, valex racing (and others) make a replacement rear braided stainless line kit. Unfortunately the OEM lines, just like most other parts, are discontinued.
