Coupling in brake Line on driver's side frame rail
 

When I ordered the brake lines (and when removed the old ones), I assumed the main line that runs from the proportioning valve back to the rear axle was supposed to be one continuous line. Well, there are two segments, connected by a double-female coupling.

Below is a picture as I was taking the truck apart. Make it full size and see the coupling in the lower right near the cab.

I think I tossed the coupling with the old line, thinking the new one was a single line from stem to stern. Thinking junk yard might be the best place. Or are these readily available and cheap at auto parts store?

Here is the same segment of rail now:

Your local parts house should have it, or if not...

Buy Dorman - Autograde Brass Fittings, SAE 45º Flare Fittings, Type - Union, Tube Size - 3/8" 490-383 at Advance Auto Parts

That's factory. The line going to the rear was two pieces.
What you're looking for is a 3/16" inverted flare union.
The Ford part number is 383057-S
Green Sales, Cincinnati, OH has 10 (800) 543-4959
Don Sanderson Ford, Glendale, AZ has 45 (623) 842-8643
There are quite a few others available, let me know if you want more names

Some trucks had 1 piece lines and some had 2 piece lines with the union. Almost any truck that has had brake repairs will have 2 piece lines, since thats whats available premade at parts stores. The unions should be female to female and are available at any parts store, autozone/napa/oreily's/advance/carquest and probably even your local home depot. Should be a 3/16" inverted flare female union.

Great info, I'll see what I can find locally, and if I strike out, Mike's contacts will come to the rescue!

THANKS!

I picked up what I thought was the right part, not yet installed, still in packaging... it says 3/16" "bubble flare."

Silly question: is that the same style part as "inverted flare?"

Not sure I understand what is so "bubble" about this, looks the same in the pics.

THANKS!

Not sure that will work. A "bubble flare" is sort of an incomplete double flare.
In the picture you can see why it's called a bubble flare.

Sorry to bring bad news but the bubble flare is the wrong one. You'll have to get the right one for inverted flares. The inverted flare seals when the nut applies pressure and clamps the flare between the tube nut and the mating surface of the union. The bubble flare seals by applying pressure to the bubble and seals on the outside of the bubble.

Alright, thanks guys, taking it back to the store tomorrow :'( and swapping for the right one.

don't be shy, just tell the guy behind the counter you need a 3/16 inch inverted flare double female union. It sounds technical and makes you sound like a nerd but anyone who has worked at a parts store more than a day should know exactly what it is. Hell, the idiot behind the parts store at autozone knows where they are, and he doesn't even know what a copper washer is. lol
And if they give you the wrong one, throw it through their front display window and go somewhere else.

Or what you could do is buy 25 ft roll of brake line, double flaring tool and fittings and makeup you own line. That way it's all one piece with no union and the right length .

In his 1st post it seems like he says he already has the new lines...

Not the best advice, but the damn funniest I have read today. And remember you have to really wind up and let that little thing fly to brake the glass.

Or it will bounce back and ping you right in the "frank and beans" and drop you like a rock, so put a little curve on it to be safe.

And by god be wearing safety glasses, fur sure fur sure. And park your vehicle assault tactical style (nose out) so you can screech it outa there yelling "evlis has left the bldg".

LMAO

line check
 

I had a failure of rear brake line and this is an item that should be checked because of gas spilling from overflow when overfilling at times,dripping on brake line causing rust thru.
