Spot on NSEU. A relatively simple theory usually proves to be the correct one. Forget about all these shlush theories or EMI/ESP etc. The only problem is that we are unlikely to ever find out for sure.
Awaiting to be shot down in flames together with you.
Indeed an interesting theory. In my last post I suggested a vacuum created by fuel restriction (waxing) could have been the reason for the cavitation, but as the actual fuel freezing temp was -57°C, it seems more logical that the vacuum was caused by another factor, such as a stuck pressure valve... But then again, in both main tanks at the same time... ?
How about the 'loose union' mentioned in the report? could it have introduced air in the fuel system?
