Re: Quick Disconnects for Fuel Lines
When my QD failed it appeared to me that it was simply a design problem. The male fitting has an o-ring recession molded into it which reduces the original wall thickness and makes it the logical place for failure when stressed. Mine appeared to have been re-connected in such a fashion to cause constant stress on the fitting so it was only a matter of time. While I agree that metal is better than plastic, if you really dislike plastics don't open the hood on any modern passenger car. Most of them are loaded with plastics including the intake manifolds, valve covers, radiators, fuel injectors, COP systems, EVAP systems, etc.
