Might be easier to put a capped "T" in the crossover line so you can drain the gas out.

I'll start off with the disclaimer that I'm not scientific or highly educated, but with my plastic pipe experiments, it seems to me that so long as the crossover pipe doesn't have an air bubble to begin with, the flow from one side to the other will quite happily go uphill several inches above the fuel level in the tank in order to equalise the levels, so for me, I'm going to leave the crossover pipe over the frame rail. I'm still not convinced, there may be something wrong with the way I did the experiments, but for now it looks like it works fine.

Almost 2 years ago, I was booed all round for my solution to removing a FULL gas tank. But to this day I'm still using it, & haven't set fire to my BOYS. The best news is I haven't had needed to remove the tank yet either. I used a VERY long crossover tube of ever-pliable Fuel Injection rated fuel tubing routed over the frame far enough to the rear to be lower than the lowest elevation of my tank. My tank cap has a breather hole.
My actual fuel lines to the carbs are the vintage BMW lines with braided cloth covers that stay pliable & are easy to separate from my fuel tap nipple.
The only practical concern I have, is that tank debris could clog the steel nipple portions of the crossover lines. I may ad a vintage fuel filter bowl in the center of my long crossover hose to trap any debris. Hopefully the tank will stop producing it.
So far my fix is still working, & I'm apparently still crazy

I knew I'd seen someone else with the same idea on here, Insubordinator, but I couldn't remember who. Have you ever run out of gas with this setup?
