Extra long fill adaptor for Daystate

Hi, I need some help.
I have a Joe Brancato fill assembly for my SCBA tank. My new Daystate Red Wolf came with a long fill connector to make it easier to connect/disconnect through the stock. What adaptor or fitting do I need to connect or swap out the short quick disconnect with the longer quick disconnect? See images.

I can fill with the shorter quick disconnect, but it's tough to get my fingers in there.

Thanks

I

Here is a warning to those using these long fill probe connectors. It appears the slide action of the sleeve is quite rough on many of these. Add that to a slightly large diameter o rings they come with and when used, the sleeve may not allow the full seating of the locking balls in the locking groove. this result will cause the probe and whip to explosively release while filling. This can result in serious injury, unnecessary pain and a destroyed o ring. This condition is quite hard to detect, so great care is in order. I am not certain who the manufacturer is, but the ones I have seen are all the same regardless of who sold them. I got mine from DonnyFL.
