No crash testing has been done.
Do you have the link to that thread?
Anyone who has concerns about insurance most likely does not know the rules and is a pointless discussion with everyone saying their two bobs worth, but nobody talking facts.
Any tank that is mounted inside a chassis rail does not need any sort of structural testing. Side mounted truck tanks or tanks that are within 100mm of the external body need to be drop tested from a large height.
Once a car has been registered any ADR rules do not apply (but the bigger tank can not affect them) and it is the individual states rules that need to be considered.
The state rules are along the lines of:
No closer than 100mm to the ground
Do not affect the depature angle
Welded to an Australian welding standard etc
These rules are more for drop tanks in street cars as our tanks would not sell if we made them suit most of these rules :)
Besides all of that our tanks are made of 2mm aluminised steel and your factory sub tank that is in the same placed is only about 0.9mm
FYI
We once put one of our troppy tanks out in the padock a few years ago and put a remote ignition source in it.
We then put different amounts of fuel in it and tried to blow it up.
We them put some aero start in it and tried again.
AS a fuel tank is not a pressure vessel and can not handle pressure over about 10 psi before distroting it did distort and would not be able to be reused, but it did not split open.
A little dissapointing really we where hopeing for something like in the movies :)
