Alan,
Why are you trying to make this so complicated. Your approach is simple enough, but you run into the problem of something electronic not working or something breaking.
You mean, when did I stop beating my wife? :laugh:
First, It is
Lloyd's situation I'm trying to deal with, not yours, Dimi's or mine. So, as a reminder:
- The only existing ports are halfway up the side of his fuel cells.
- He cannot make any additional ports in his fuel cells.
- Therefore, he cannot have "a bottom cross over line that keeps the fuel tanks even"
Second, as an EE I beg to differ with your implication re: electronics and reliability.
Properly designed an electronic solution is
always more reliable than a mechanical one. I don't push them that hard because not everyone is in a position to design and build their own. The only one I proposed is extremely simple and could be made
way more reliable than any fuel pump.
Thirdly, my later solutions
don't use any electronics.
Finally, my earlier posts show that you, Dimi and I are all in violent agreement about how to do this
when you can have "a bottom cross over line that keeps the fuel tanks even".
Lloyd (the OP) does not have that option.
