Honestly, I am not taking an attitude, just replying to comments.
Really it's no one's place to say what is not worth my time or money. No one has a right to say that to anyone. I work two full time jobs, and you absolutely do not know me to talk down to me like I am your son. I just want to make that clear.
I can say with absolute certainty that I will never talk down to you again...
Good luck with your mod..

As you're seeing, snipping back will just drive potential help away.

To clarify, for myself, you want to increase the size of the fuel crossover line to allow for easy two tank fill up utilizing only the right side opening. And this is so you can install a Fuel Gauge on the left side opening.
Do I have this right?
When the factory went to one piece tanks for Softails (and other models) they have the tank going over the back bone to allow for filling from one side. I don't think you could get the crossover large enough that it would nullify the need for them to be a true single tank. I think even with a 3/4" line(which would look awful) you still will be sitting at the pump for a while waiting for the fuel to migrate to the left side tank. This would likely lead to impatience and never filling up completely.
I get what you want, but I think you are going about it from the wrong side. Have you thought about trying to fit a later model one piece tank on your bike? Maybe after market tank? Either way you are painting things so maybe this would be a better direction. Good luck.

There is nothing to gain. The cross over line just keeps the level in the two tanks even.
Nothing else. The fuel supply to the carb is on the left side. It could be 5/16 or 3/8
depending on the petcock and the type of carburetor

OP, the cross over hose on the bottom and the cross over vent on the top would have to be huge.
And would only benefit you when refueling.
It works via gravity, not pressure.
The pump pushes gas too fast.
Now that I've explained the physics of it, good luck.
