I'd call up Airguns of Arizona, if that's an option for you. I screwed up my gauge on my 400 recently and they were able to get me the right stuff quick!

Thanks Tom, just got the parts I need from Airguns of Arizona. and replace the manometer and the feeler valve. Now it has a air leak thru a hole beside the gauge, do you know what cause it ?, what can I do to fix it ?
Thanks
Juan

Juan, is that hole your referring to below the gauge and drilled into the body of the receiver? If it is, that's the vent hole for the regulator and would indicate you have a O-ring leaking on the regulator.

Hi JK, this is the hole I am referring to: http://img.photobucket.com/albums/v386/HitDroad/One%20day%20at%20range/20161114_164811_zpsxwe1nwmh.jpg

Replace one of the 4 oring of the regulator.

Here you will find the oring size (last post):

I hope that one of the 2 external oring are damaged. If not you will have to dismantle the reg to replace inner orings. It is quite easy (refer to ernest video on youtube).

You will need to set back the regulator to 160bar. To check the pressure I have an easy way if you do not own a chrony:
- fill your boss to 200bar or more
- remove the bottle and normally the air does not escape from the reg (pressure reg is below 200b and the reg stay close)
- put back the bottle and fire 1 or more shots to decrease the bottle pressure (let's says to 180bar)
- remove the bottle and if the block keeps the pressure inside repeat the process
- bottle back
- 1 or more fire .....

Once you can ear air escaping the block trough the bottle connection -> you are close to the regulated pressure

It seems to be a long process but with practice you can approximate the reg pressure for free in few minutes.

Thanks for all the inputs. Are this (show with the yellow arrow) the regulator of my FX Boss ?
Also, can I remove my boss air bottle safety even if it has pressure ? Thanks

Juan, as far as I know you can remove the bottle safely, The FX400 and FX500 are capable anyway and that's why I'm assuming you can. You can unscrew it slowly until it starts bleeding air and watch the gauge go to zero. Even after you bleed the air off the gauge there may still be some pressure trapped behind the valve so cock the gun and fire it make sure. The picture you had is the regulator. It may just be one of the two outer O-rings leaking. I'd replace them first and reinstall the regulator and see if that doesn't fix the leak. If you do have to disassemble the regulator get some good measurement of it before you take it apart. A digital mic works well. Here is a link to Ernest Rowes website that has lots of good information to help you out.

Thanks Jimmy, Dreuf and Tom for all your inputs, I really appreciated it. I will ordering the o-rings to be prepared for disesamble 

Thanks again

Take care Never fire your boss without air pressure in the block!!!!

You could damage valve stem. If pressure remains fire it one time ONLY and unscrew slowly the connection part between bottle and block.

All fx bottles on royal block own a valve so it should be safe. Anyway unscrew slowly the bottle (we never know ...)

 

[Juan]

Last question, if I get the regulator (19043) from Airguns of Arizona, I will need to adjusted it or it came all ready adjusted?
Thanks again
Juan
