I'm in the process of swapping a 460 and ZF S5-42 into my '69 F250. I've converted the manual clutch linkage to hydraulic using '88 F250 master and slave cylinders and mating factory clutch line. I'd like to cut and splice the 5/16 hydraulic tubing since it's way too long. Has anyone successfully done this?
If so, how did you do it?
I've heard of some people using compression fittings.
Do you have to support the tubing from the inside with a sleeve? If so, does the sleeve impede the hydraulic fluid flow and cause a problem?
Also, does anyone know the specific official name for the fittings that attach to the master and slave cylinders? Mine push in, seal against a type of O-ring and are held in with a roll pin.
If I can't successfully splice the nylon tubing, I thought I might be able to find the fittings somewhere and make a custom hydraulic line.

 

any hydraulic shop can help you, I dont know the name of the fittings but I tried to do the splice to help a cistomer who had cut his line and after a not so successful , "fix it as quick as possible " splice, and had a new one made . youll be much happier when you dont have to fixe it again later ...and later...and later,bob

 

Is this nylon hydraulic line the same as the hard nylon fuel injection line?

 

I believe its thicker , bob

 

Sorry, Bob, but the hydraulic/brake shops in this neck of the woods (Raleigh, NC) act like they've never heard of nylon/plastic hydraulic line. Maybe I haven't hit the right one, but I've had no success either locally or on the web in finding some professional info on splicing this line. I finally bit the bullet yesterday and cut the line. I found that the walls of the tubing were much thicker than I expected. Thick enough that I decided that a standard compression fitting would work. I got a 5/16" compression union, cut out about 18" of unnecessary tubing and spliced them together. With fewer bends and switchbacks in the hydraulic line, bleeding should be easier. I'm going to put the whole system back together today and hope for better results than the first time.

Cheers,

those lines breaking due to cold are getting common up here ,in alaska. probably why the local hydro shop has the parts, didnt mean the splice wouldnt work , just didnt want to suggest something without knowing your level of expertize, respectfully,bob
