What size tubing do I need to get to make new lines to go to the trans cooler, 3/8? Will a single flare be ok or do I need to double flare the line like the brake lines? What about the size of the line that goes to the vaccume modulator?
ITS EITHER 5/16 OR 3/8 SIZE LINE... ONE OF THE 2 BUT I AM THINKING 3/8. U SHOULD BE ABLE TO GET BY W/ A SINGLE FLARE. AS FOR THE VAC. MODULATOR, PROLLY AROUND 1/4-3/16. HOPE THIS HELPS
Yea, brake line is what I plan on using for both the cooler lines and the vaccume modulator. Why did you not like it? I used 3/8 brake line for my fuel line and I found it to be pretty easy to work with.
If you want to save yourself a headche later - run a short pieces of line from the transmisison to down below the trans pan. Then put a coupling there. If you have to drop the transmission it makes it a whole lot easier to break at the pan and leave the stubs attached to the trans. Cleaver
Jamie, I think NAFORD was referring to how hard it is to work with the braided line. I have never worked with it, but it seems that keeping it from fraying would be a major hassle. I agree that regular brake line is pretty easy to work with once you get "soft hands" and learn to bend the tubing gently enough to not kink it. Cleaver, I like the coupling idea...even a quick-release setup, maybe. I am amazed at how many times in a year I have disconnected the trans cooler and a quick release would be nice to prevent all the fluid spills.
3/8" for the transmission cooler line w/single flare is fine. 5/16" for the vacuum modulator to the intake. Just did this on my 85 Bronco. Also, I agree with making the tranny lines a two piece type. Although I have made mine disconnect about 2" rearward of the bellhousing just in case I needed to remove my transmission, the lines would come out with it. Don't want to mess around with those 90 degree fittings on those auto trannys too much.
With a 6 cylinder, it's really easier to me to just pull the engine and trans both out if you need to do something to the trans. I usually just unhook the cooler lines up at the trans cooler and strap them to the side of the motor and then lift it all out. 6 cylinder engines are very quick and easy to pull. I can drive my car up to our engine hoist and have the engine and trans sitting on the ground in an hour.
i made the lines out of brake line and used coulpers and it leaked yes i yoused the correct parts and could not get to stop that is why i used braide lines
