My 08 C5 is leaking from the rack where the fluid pipes attach, I have had both pipes replaced and its still leaking. i now have no idea what to try the leak is from the pipe connection. Does any one have an idea to try, as I say both fluid piped are new so the o rings / seals are new. Could the clamp be bent? Is the clamp replaceable on its own or is it part of one of the pipes? Can I fit oversized seals?
