Ford boys, fuel tank questions

[Vimes]

Wasn't sure where to put this, so thought it would work here.

One of the problems with my project has been, where to stick the fuel tank? I happened across a link that showed that Mercedes uses a saddle tank, and further research shows that 2015+ Mustangs have a 16 gallon saddle tank that rides over the driveshaft. I think this will solve my biggest problems with a tank.

SO, the questions are, have any issues with the tanks working correctly? I understand there's several methods for transferring fuel from one side of the saddle to the other. Also, any issues with higher pressure/volume fuel pumps? Figuring it'll be a lot easier to get a high pressure/volume pump for a Mustang than a Mercedes as well. I'd like to know if there are any inherent problems with this possible solution. I'd already planned on cutting an access port in the bed of my truck for pump access so cutting two access ports would not be a problem. I also already planned on doing a driveshaft loop.
