They leak!!what problems are you having with them?
Alright, MR Google, I've searched and come up with nothing.O yeah... ;D
That's the funny thing. The fittings and all look absolutely brand new, but leak like a sieve.Ask your parts guy at the local merc dealer,
he'll know more than I do.
I'd replace the entire hose with a new OEM hose.
If the O-rings are gone, I'd be questioning the reliability
of the internal valves of the squeeze ball.
