Gidday boxhead,
VSB 14 is the "vehicle standards bulletin" that relates to the National code of practice for light vehicle construction.
http://www.infrastructure.gov.au/roa.../vsb_ncop.aspx
In the subheaded sections there are a number of checklists that builders, engineers or inspectors can make reference to when checking compliance for specific areas of construction, or components.
So for example you go to the section on fuels systems and printout the checklist that relates to your type of fuel system, then check the boxes as you go through the issues identified. If you can tick off all the boxes, and explain the modifications you have made on the way, it makes the engineers job much easier.
Thats the general idea anyway. It gives you a heads up on what you need for compliance because the rules are also explained in the same documents.
