are you sure it's not the pump that's leaking?I've tried everything to get it to stop leaking. It leaks right from where the pump fits into the reservoir. I tried siliconing it but then it ends up leaking again. I bought a rubber grommet that fit perfectly into the hole and was snug around the pump nozzle too, still leaks. Does the dealer carry the original grommet? How much is it?
they're about $20 from the dealer. worth replacing,
you'll be amazed at the pressure difference.
