Default Help! Blew off quick disconnect and it won't stay on!

Yesterday I was driving and lost fuel pressure. Pulled over and my quick disconnect at the factory feed line had blown off. I have the FAST Rails with the -6AN braided line up to the disconnect where it meets the factory feed line. No matter how hard I push as soon as I turn the key and pressurize the system it comes back off. What can I do? Could the barb on the factory feed line be worn down too much or is it more likely that the plastic piece in the quick disconnect got messed up? I also have the evap tuned out and capped at the line and intake.

A while back there was a few threads about the quick disconnects fatiguing over time and will not stay locked on the barb of the factory fuel line. I want to say people were replacing the white plastic clip and and were taking a thinner hose of some sort, and sliding it between the metal hardline and inside the acutall fitting to keep the collar flared out.

Interestingly enough, it looks like Russell may have redesigned these fittings so there is a thread-in aluminum collar in the back to prevent the fitting from blowing off. Here is a pic for reference...

Yes get the new design the old design is horrible.I've have 3 different fitting pop off leaving me stranded several different times. Russell blamed it on me installing them incorrectly...
