Fittings and threads

[ChiScouter]

I just bought a 94 F350 4wd dually dump, its like 50 miles away and I may need to replace the brake bleeders and brake lines. I would like to pick them up on the way to the truck, but I don't know the size of the line, or thread type. Can you guys fill me in if the brake lines are metric or english, the size, and line dia? Also the thread size and type for the bleeders for the rear wheel cylinders.

Go to your local parts store and tell them you want to see a wheel cylinder for that truck. Then see what thread matches.
