they use Earl's fittings but i thought they used to use Russell fittings, you can buy the fittings you need off their website to repair your leaking lines. if that doesn't say something right there.. lol (worded akin to making your own custom lines, but they only offer the 4 they use to make their own lines)

after seeing several sets leaking i just kinda shrugged and said "well makes sense that they sell the repair parts...".
