Fuel Tank Size Tweaking

[Stargate525]

This isn't a post about procedural fuel tanks.

I was playing through career mode, and updating some of my designs to replace the smaller fuel tanks with the larger ones, and it got me to looking at the values of them both. Right now, the only difference between the large fuel tanks and their smaller cousins is that they are a (very very small) better value for money.

To me that doesn't make sense. I mean, if you've got two separate tanks as opposed to a single bigger one, you have valves and pipes and casing that's doubled. It's inefficient as a function of weight as well. My suggestion is that either the smaller tanks get a slight dry mass increase, or the larger ones get a small mass decrease, so that doubling the size of the fuel tank only increases dry mass by 1.8 or similar. More realistic, in my opinion, and also gives you a little more incentive to choose between them.
