Page 5-6 lists the O rings and there is a lot more than in your kit.
Looks like your kit has frame seals and poppet valve.
Normally the Mfg. do not supply the tank seals as they use special tools to strip,
usually a pin spanner.

4.9.0001 O-Ring 4,0x1 O-Ring 4,0 x 1,0 F1
4.9.0002 O-Ring 7,0x2,0 O-Ring 7,0 x 2,0 N1
4.9.0015 O-Ring 18,0 x 2,0 O-Ring 18,0 x 2,0 N1
4.9.0016 O-Ring 3,0 x 1,5 O-Ring 3,0 x 1,5 K1
4.9.0017 O-Ring 9,0 x 1,5 O-Ring 9,0 x 1,5 N1
4.9.0018 O-Ring 10,0 x 1,5 O-Ring 10,0 x 1,5 A1
4.9.0101 O-Ring 7,65x1,78 O-Ring 7,65 x 1,78 B1
4.9.0103 O-Ring 24x2,5 O-Ring 24 x 2,5 B1

The o-ring that let's go first is usually the cylinder one. Replace that one and see if it fixes it.
In your case, part nº 4.9.0002 O-Ring 7,0x2,0 (should be the light green in your photo).

The valve is normally the second to let go, it's part 3.4.350.121, and is in your photo.
The other ones should be the 4.9.0015 and the smaller 4.9.0001.
You shouldn't need anymore o-rings for a simple service.
Bear in mind that you don't need to open the regulator to change those, but there are another three o-rings inside, part nº 4.9.0016 (2x) and 4.9.0017.

Get that kit, or if there is one with more o-rings, get that one.
You can also buy o-rings here: https://www.sove.pt/ (it's near Jamor)
Tell them you want o-rings for compressed air, with an NRB of 70 or 90 (better).

Any doubts, fell free to PM me.

Hope this helps
