Just to expand on this as I am considering a blown fuel tank to help draw fuel from 70mm below the spray bar centre line in my application, I went to 'The Shed' to test.

Using 3cc of Model Technics D1000 and 2cc of hot water with a sprinkle of instant coffee to use as a water dye, here is a picture of the test result inside a 5cc syringe. I apologise for the out of focus result, sadly photography amongst other things is not one of my strong suits.

As you can see, there is nearly 2cc of water at the bottom which readily formed and settled, a smidge of 'froth' (the combination of which looks like a great pint of traditional hand pulled ale) then the diesel fuel on top.

Here is why I am looking at pressure blown fuel tanks. I may be able to raise the tank above the spray bar height but lack of space dictates it is better as is if possible. There is NO possibility of a conventional aeroplane fuel tank layout with this. Just no space!
