SCBA tank to Marauder fill hose

[cca50]

I am trying to set up for a PCP purchase. Just last weekend I discovered an old friend that has a commercial compressor. I got an excellent deal on a mid sized SCBA carbon fiber tank and not need a fill hose setup. Does anyone have a suggestion on which way to proceed or by chance have an extra they might be willing to part with at a reasonable price?
I am attaching a pic of the fill hookup on the tank where the hose will attach. This is not the actual pic, he had several of the same tanks for sale
Thanks

So if you are paying attention, there is no need for the extra gauge in the line?
Thanks for the link.

you don't need it unless your gauge on the gun is hard to see, the marauder is easy to see, I use the add-on gauge for my Texan when filling on the bench.

I replaced my old valve with this set.
