Tuning PP700SA help

New to forum new to pcp did all the mods mentioned. Questions?

1. How many hand pumps from empty. it does not seem to fill after emptying and modding no leaks.

2. With huma pump installed and stock reg screwed down to bypass. Supposedly your supposed to leave gap on air tube but when pumping the fill probe unscrews it while pumping will it tighten when full of air?

3. understanding the valve why are there holes around it surrounded by 2 brown orings if the hole lines up to loading block hole why do you need the other holes, would it be good to fill it with jb weld.

4. If stock regulator is bypassed would jb welding the hole around trigger, the reg adjustment hole make flow better. I have seen Mike Nelson videos. I don’t want to drill the regulator I just screwed reg down to bypass for huma.

5. Is there a regulator you can buy instead of huma that goes right in place of the stock reg.

thanks sorry for so many questions
 
1. Not sure how many pumps it will take to refill but make sure the hammer is pulled back. I fill with an scratches.

2. I tighten my air tube down (just lightly) but I also put a v notch at the end of the air tube so air can escape so the regulator will work.

3. Some people do JB weld the other holes and leave the one lined up up to the transfer port on the block. I didn't do this because would be easy to make it slightly off.

4. You do not have to jb weld that hole as it does nothing with the stock regulator in there. I did it mostly for looks so there wasn't a hole there.

5. I haven't seen any other regulators that are a stock replacement unless custom built ones.

Hopefully I kind of helped answer some of your questions. If you have any more questions I will subscribe to this so I will see them and can try and help
