Can you link a quick connect to AN-6 fitting for the feed line? I'm having a hard time finding one.
Im not at home and dont recall the size of the return line but here is a link for both 3/8 hard line and 5/16
There are cheaper options but these two look similar to what our current retention clip system is.
