c) a first endplate adapted to one end of the upper cylindrical member, wherein the first endplate is a pressure release member; and

ii) a replaceable pressure retaining and relief system, the replaceable pressure retaining and relief system configured to—

a) retain the reusable container components in a fixed configuration when the contents of the vessel are below a relief pressure; and

b) allow reuse of the reusable container components without repair by releasing contents of the vessel at the relief pressure.

2. The vessel of claim 1 , wherein the replaceable pressure retaining and relief system is configured to open the vessel at least 2%, relative to a surface area of the vessel, within 1 ms of contents of the vessel reaching the relief pressure.

3. The vessel of claim 1 , wherein the replaceable pressure retaining and relief system is configured to retain HHO gas within a storage pressure range.

4. The vessel of claim 3 , wherein the second chamber is in continuous fluid communication with the first chamber, the second chamber configured to store at least a portion of the produced HHO gas.

5. The vessel of claim 4 , which is configured for passive transport of HHO gas from the first chamber to the second chamber.

6. The vessel of claim 1 , wherein the second chamber is configured to contain less than a 1 hour supply of HHO gas.

7. The vessel of claim 1 , wherein a controller is configured to control an electricity supply to the electrolysis cell to maintain a volume of HHO gas in the second chamber within the storage pressure range.

8. The vessel of claim 1 , wherein the the pressure release member is sized to release at least a portion of the contents of the vessel when a pressure of the vessel reaches the relief pressure.

9. The vessel of claim 8 , wherein the pressure release member is non-reclosing.

10. The vessel of claim 9 , wherein the pressure release member is configured to open the second chamber.

11. The vessel of claim 9 , wherein the relief pressure is less than the lowest failure point of the vessel components.

12. The vessel of claim 1 , wherein the replaceable pressure retaining and relief system comprises at least one elongated retaining member.

13. The vessel of claim 12 , wherein the at least one elongated retaining member comprises an all-thread rod.

14. The vessel of claim 12 , wherein the replaceable pressure retaining and relief system is configured to open the vessel when the at least one elongated retaining member yields.

15. The vessel of claim 1 , wherein the vessel is configured to open the first endplate to form a vent area within 0.1 ms of contents of the vessel reaching the relief pressure.

16. The vessel of claim 1 , wherein the replaceable pressure retaining and relief system is configured to open the vessel upon detonation of HHO gas in the first chamber and/or the second chamber.

17. The vessel of claim 1 , which is adapted for installation onboard a vehicle.

18. The vessel of claim 1 , wherein the replaceable pressure retaining and relief system is configured to form a vent area at a top of the second chamber.

19. The vessel of claim 1 , wherein a controller is configured to control an electricity supply to the electrolysis cell to maintain a temperature in the first chamber of less than 65° C.

20. The vessel of claim 1 , which is in communication with at least one injector, the at least one injector configured to deliver at least a portion of the HHO gas to diesel particulate filter regenerator system.

21. The vessel of claim 1 , which is in communication with a plurality of injectors, the plurality of injectors configured to introduce at least a portion of the HHO gas to at least one combustion chamber inlet of the internal combustion engine.

22. The vessel of claim 21 , wherein the plurality of injectors comprises:

i) a first injector configured to deliver a first portion of the HHO gas to within 3 inches of a first combustion chamber inlet of a first combustion chamber of the internal combustion engine;

ii) a second injector configured to deliver a second portion of the HHO gas to a second combustion chamber inlet of a second combustion chamber of the internal combustion engine; and

iii) at least a third injector configured to deliver at least a third portion of the HHO gas to at least a third combustion chamber inlet of at least a third combustion chamber of the internal combustion engine.

23. The vessel of claim 22 , wherein the first injector is configured to deliver the first portion of the HHO gas during a portion of an intake stroke of a first combustion cylinder, the first combustion cylinder comprising the first combustion chamber.

24. The vessel of claim 23 , wherein the during a portion of an intake stroke is when the intake stroke is at an angle in the range of 0-40° from top-dead-center.

25. The vessel of claim 1 , which is in communication with a heat exchanger, the heat exchanger configured to receive at least a portion of the HHO gas.

26. The vessel of claim 25 , wherein the heat exchanger is configured to receive an engine exhaust stream and/or an engine coolant stream.

27. The vessel of claim 1 , wherein an electrical supply to the electrolysis cell is isolated from the second chamber.
