Interesting. Just done the test 06 and got the following values....

Screen 1 -
24.7 / 1.8 / 26.5L

Screen 2 -
4.7L Phase 1


Thanks for the hint. Didn't know I could check this. So I believe this tells me where my missing fuel went which is good. - definitely confirmed my original theory.

So 2 questions left...

1. How do I get the fuel across to the other tank so that it computes it correctly? Will it gradually go over by itself over time?

2. What could have made the fuel pump stay on? Ignition switch? Sticky fuel relay?
