In general: every 5 years: hydro test. "Officially" dead after 15 years from date of manufacture. Any reputable place won't fill them without a valid hydro and you won't get a reputable place to hydro test a cylinder that is more than 15 years old. If you have a Shoebox or other compressor, you can fill them after that, but most usually fill to a reduced pressure for a seat of the pants "safety factor".
I'll err on the safe side always if I have to be around it.

He says in the dive world some places people even refuse to hydro ANY aluminum tank, so apparently there is some variability within the industry ??

After some more reading>>>> it's because they are steel. As long as they are protected from corrosion, service life is practically, "lifetime". They are heavy though... ~34 lbs for an 80CF size and ~44 lbs for a 120CF size. Unfortunately, they only are rated to ~3500 psi. I rather enjoy the amount of air/fills I can get from a 4500 psi CF tank, along with it's very light weight. In any case, it's nice for folks to know about this option. One shoe size does not fit all...
I guess what I am saying is, if I get the proper connections to fill the Marauder, will those connections fill other pcp airguns?…Thanks…BCB

Out of my seven pcp guns, five use something different.If/when you have several guns, setting them all up to use Forster’s quick connect make filling them easier.
So, does the Mrod come with the Forster set up and you change other pcp's to that quick connect. I assume it is the male end on the rifle...Are gauges needed on the scuba tank, or is there one on the rifle that is used to indicate "full charge"...Thanks again...BCB
The regulator you get will depend on what type of tank/valve you get. The one you linked to will for for the typical SCUBA K valve. If you get a SCBA tank, it will almost certainly not use that valve (either a CGA for firefighters, or a DIN300).Figure out what tank you are getting first, then get the fill equipment for that particular tank, and make sure that you can get your tank filled with the valve that you get.
If a gun takes 3000 psi to fill and the tank only has 3000 psi in it, then you only get one (1) 3000 psi fill.
