A&S BMW sends me email-offers from time to time, the latest being a fuel line quick release coupling that is "Die Cast Zinc and Nickel Plated". Does anyone have any opinions of this being a a good investment or a waste of money?

The reason I'm asking is that I've been led to believe the stock couplings for my 2003 R1150R are a little fragile and could be improved upon.
