Hi!
Hold on!
There is no problem with your tank as long as there is not air bubbles when you run the engine as normal!
The engine will eventually cut out in a long dive! But that is no problem because you cannot dive for that long ...after just a few seconds the ground will grab you!

You should not! I repeat NOT istall the lines in your tank so that the fuel line can be bent forward!!!!
The standard procedure is to have the clunk line 0,5-1cm from the back of the tank ...and not bother with the fuel line going forward in a dive...because the fuel line should not!!!!
