Default 1964 Pontiac Grand Prix Fuel/Brake Line Routing and Location

Does anyone have photos or know how the fuel lines and brake line going to the rear of the full size '64 Pontiacs are routed?

I'm replacing the fuel lines in my '64 Grand Prix with factory A/C (i.e. it has a vapor return line besides the regular fuel line), and I didn't seem to take any good photos years ago when I disassembled the fuel lines. From what I believe, there's a small, double line brackets on the inside of the driver's side frame rail that hold both fuel lines. Then there are clips that hold the rear brake line above the top fuel line. Can anyone verify this is correct, or is the main fuel line and brake line held by the brackets and then the return fuel line clipped above the bracket?

I have reproductions of the factory brackets/clips, but not sure how the lines are routed and I'd like to get it right both for appearance but also function. Thank you!

I have a 63 GP w/ AC. If that is close enough, I can take pictures tomorrow?

That would be great, gtoguys! I'm sure that the locations are probably the same or very similar. Thank you!

If the pictures aren't enough, please pm me. I took these with my cell phone at night in the driveway.

Since I can't get more than one picture at a time, it will take a few replies.

You can see, this is a driver car. No show queen.

Thank you, gtoguys! That helps a lot and was very nice of you to take photos for me. I have a couple questions.

1) I assume that the fuel lines are the ones clipped in those brackets on the frame and the brake line is the one that is in front of those two lines. Can you tell which lines are which?

2)It's hard to tell in your photos, but do you know how the brake line (i.e. the line in front of the two lines being held by the bracket on the frame) is supported? I thought that there's clips that clip the brake line to the other two lines being supported by the brackets. If you can tell me how that third line is attached and what the clips look like, that would be great.

Here you go: Blue tape is Brake, Yellow tape is Fuel, White tape is fuel return. The last picture without any tape is the 2 fuel lines just before the fuel tank. If I can help more let me know. Please send a personal message to me.

GTOGUYS, Great photos. I am replacing the fuel and brake lines on my 64GP
and this is a big help. Thanks AZ64GP for posting this question.
It also has the 1/4 inch fuel return line. I remember the return line attaches to
either the Fuel or Brake line with " S " style clips just like your pics.
The 3/8 fuel line and brake line snap into the clip with 2 openings.

Thanks again, Rich
