hi guys,

do you have any experience how to open this type of air tank ? do i need to take out the gauge meter first?

It seems to remove the fill port cover you must remove the gauge,after this you probably can access to flats or holes and unscrew the cap and access to the check valve (45 and 46) o ring and screw. Bad oring or dirt-debris in the check valve zone can cause a leak thru the fill port.
Degass the tube first,of course.

Here is an exploded view for you. These are very easy to work on and the extra orings you might need should have come with the gun along with the tool to remove the guage..  Just make sure it is empty of air and remove the guage,  barrel band and then unscrew the fill assy. There is a little screw with a small oring on it that seals the fill port. Might be bad oring or have dirt on it.  HTH

I've replaced a few of them o rings on both my SPA M16 and PP700SA, very easy to do.  Pretty common to have those go bad on most guns with a probe.
