BUT!!! The more fluid, the lower the percentage of gunk. In transit surely this stuff is moving about a bit and there is a lower amount of stuff that goes through or something, or at least it's going through in a lower concentration? Like the less dense fuel follows the fuelling route faster and easier than the more dense gunk/chickens/nitin spunk.
Like if you make a cup of tea with one sugar. If you put half a cup of water in you can taste the sugar more than if you'd made a full cup?
Or another interesting analogy could be when you strain a saucepan of boiled potatoes. If you have lots of water you don't notice the little potatoey grainy crap so much, but if you had a minimal amount of water then the potatoey grainy crap doesn't strain off so well, it just sits around the holes in the collinder.
