Along with the air passage connecting the output pressure of the first regulator to the second regulator, the following penetrations in the trigger block are at high pressure:
1. Fill probe
2. Bottle pressure gauge
3. First pressure regulator
4. First pressure regulator output gauge
5. 2nd regulator
All would be potential points of failure.
