Veronica, I did a serch here and found 3 pictures you have posted about a year ago showing some lines running along the transmission area and up around the outside of a front frame rail. I'm looking for pics that show the under side from the drive shaft back to the rear end and the gas tank.
Hey Greg :smilie I'm sure Veronica will come up with diagrams, pics, or something that will be extremely helpful. She always does.
In the mean time, here are some pics that may help. I have a 65 FB 289 with drum brakes that had single exhaust that I converted over to duals. I replaced the brake lines to convert to duals. I also replaced the tank to pump fuel line using the 5/16" prebent. The brake and fuel lines run parallel from the front frame and along the drive shaft tunnel. They share the same fasteners. The fuel line then turns and runs up and around the left rear wheel edge. It then nestles in a recess between the tank, turns, and runs along the leading edge until it stops near the sending unit. Then you connect it with a flexible hose. I hope the pics are clearer then the way I wrote this.
Hi again. Thank you, 65 Fixup, that is very kind of you. The pictures that you have are very helpful, as usual. Those are a 65, and the emergency brake stuff is different on a 66. For one thing,on a 66 the cables droop down under the frame rails, instead of going between the frame rails and floors. The fuel line stuff is essentially the same, though. Here are a couple of pictures of an unrestored 66 convertible that might help. I'm still looking for pictures of a 66 fastback. I know that I have them of some Shelbys, but, I'm having a little trouble locating them.
Thanks for the info and pics! I can see a lot from your pics. I need to get the flex rear brake line that goes on the rear axel so I can hook up the rear metal lines that go to the rear brake cylinders. I see they make a different rear flex line for a 65 and 66?
I'm not sure if my car had duel or single exhaust from the factory, cam with no motor/tranny and etc. It was a A-code, 4 speed, rally pac, style steel wheels and some more options. All this would lead me to asume it had duel exhaust. Are the holes/brakets that are under the hump/tunnel the same as a single or duel exhaust? Are the fuel/ brake lines really that different between single and duel?
I see your breather line from the rear axle is lond and runs to under the rear seat, is this correct? Where does it go from there?
Where does the rear brake flex line meet up with the steel line and how does it hook to the car?
I have one peice brake and fuel lines from front to back. It's hard to tell which end is front or back?
I printed all your pics and I also went on ebay looking for 65/66 cars that had a lot of under car pics. I found many and also printed them as well. I think I will be ok with what I have/read from everyone, I hope?
I knew that the parking brake is different then a 65, but thanks again! Still these pre-bent lines are kind of hard to figure out how/where they go. I will figure it how I'm sure.
My car is totally a bare shell and now I'm starting to put it back together. I know there's just about everything out there to buy, the hard part is know exactly what I'll need. I'm converting to front disc and going to a T 5 tranny. I know I will run into not knowing/having the correct parts in getting this car back together at several points. That's why I'm here asking questions.
Hey again Greg I'm pretty sure the brake lines are the same for a 65 and a 66. At least the catalogs say they are.
To answer some of your questions, the brackets that secure your brake lines that run along the driveshaft tunnel are the same for single or dual exhaust. For dual exhaust, you have to move the flexible brake hose near the rear axle away from the exhaust. This will cause you to have a differently bent brake line that runs from your distribution block or proportioning valve back to the flexible brake hose near the rear axle. It will also cause you to have different rear axle brake lines because the junction block is in a different location. The first 2 pics (#2442 & #2444) are from my 65 FB (289 A-code 4-speed, same as yours) when it had single exhaust. Note the junction block was right on top of the rear axle. Also, that is the correct place for the axle vent tube to exit. You will have to purchase a new rear brake hose. It has a bracket which mounts into the old location but moves the junction block to the front of the axle housing and away from any exhaust pipes (pic 0143). You will also have to relocate the bracket that holds the flexible brake hose ( pic 0206). I made the bracket in that picture before I realized that the Mustang suppliers sell it for $6 Pic 0202 shows how the rear axle brake lines connect to the new relocated junction block.
I used the prebent brake lines and fuel lines from NPD. I'm not plugging them. They're just super convenient to where I live. At the stage you're in with your build, they should be pretty easy to install. The prebents fit really nice with just a minimum of tweaking. Hope this helps. Let us know how it goes.
As your rear axle turns, it builds up heat which in turn makes things expand. It needs a place to vent when heat builds up as well as a source to draw air back in when things cool down and contract. The axle vent tube goes into an open place in the body of your car. If the tube wasn't there, your axle would vent OK but would get full of road crud, water, etc,. Having the tube go into that open space allows venting and keeps things clean.
Speaking of the brake lines in the rear, when I first got my 66 one of the brake lines going from the distribution block on the rear axle to the passenger side had wire coiled around it, the one to the drivers side didn't. I went ahead, and found some thin wire and wrapped my replacement brake line as the old one had been. I Was just wondering if this was something that was factory original?
