Replacing the fuel and brake lines?

Oh man, yep that is bad, I would use this guide to help you splice in the brake lines, you can use rubber hose for the fuel and vapor lines. You can get new lines and couplers from the auto parts store.

Here are the fuel and vapor line diagrams, check out the images (below). Let us know how it goes.

I don't think you have quite understood what I'm asking for. Like I said, on the underside of the driver side, there are five tube lines as the picture I sent in the previous thread illustrates. After doing some research, I have been able to identify what 4/5 of those tube lines are, including their respective Toyota part numbers. What I'm looking to determine is what the fifth tube line represents.

Here are the details of those tube lines in random order:

1) Fuel Main Tube Part #: 77251-07010

2) Fuel Return Tube Part #: 77255-07010

3) Rear Driver Side Brake Tube Part #: 4732207010

4) Rear Passenger Side Brake Tube Part #: 4732107010

5) ????????????


Can you please identify what the fifth tube line is including its respective Toyota part # and what it's called? Additionally, if you could provide a diagram that illustrates those tube lines in the underside of the car, it would be greatly appreciated. Unfortunately, the diagram you provided does not meet my purpose.

Thank you

There are two fuel lines, the two with the black clip, one is high pressure fuel and the other is the fuel return line. Just follow the lines, you can see where they go. We don't have diagrams that show the lines and what they do sorry.

Please take a good look at the attached picture. As you can see, there are a total of 5 tube lines on the underside of the driver side. I have been able to determine that 2 of them are brake lines and that 2 of them are fuel lines (the main fuel line and the return fuel line). So, now we are left with only one tube line that remains to be determined what it is. The question is what's the name of it? Once I know what it's called, then I can look into finding out its respective part number, so that I can buy it.

Thank You!

Sure, please follow the tubes to see where they go, you will have 2 brake lines, 2 fuel lines, one pressure the other return and an EVAP line which will go to the charcoal canister.

When splicing double flared brake lines with the suitable fittings and when splicing fuel lines with compression fittings, how tight are they supposed to be tightened? A 1/4 turn, 1/2 a turn, a full revolution turn or until all the threads are screwed in?

They need to be medium tight, there is no way to get a torque spec, also, once the job is done look for leaks, and if necessary tighten to help stop the leaks. Let me know how it goes.
