Anyone used the QD style to AN fittings for their return line?

[MrOneEyedBoh]

I bought the earls fittings for the return line patch in place of the HFCM. Now Im wondering if I should just go with the QD style fittings that is offered. I didnt go with them originally because it says GM style ( or something ) so I didnt put much thought into it. But looking around the web, I see people are using these on all makes and models. I just didnt know if they worked for our applications/pressures ( I dont know what goes thru that return line PSI wise )
