If you’re cutting the tank anyway, and doing away with the stock fitting, you should have enough room to add a second hole the same size as the sending unit. This would allow fabrication of a plate with both straight through bulkhead fittings and lines mounted to it that uses a factory gasket.
If you’re having it cleaned enough to cut holes, and it’s clean enough to weld, a ring can be welded to the top surface sufficiently thick enough to tap threads.

I thought about drilling out and re-tapping the outlet for the original fuel line (plugged in the photo I linked), but decided it wasn't really that important for my application. The advantages for a carb are lower fuel temps but vapour lock is not an issue with my rig.

McRobb sells a pickup/fuel level with what ever size fittings you need. I have one with a AN-10 outlet and AN-8 return gauge was dead on !

I don't think he makes one for 67-72 F100s, but I will ask, that would be handy

FWIW, I've done it both for fuel pick up and return.  If installed correctly, no issues with a bulkhead type fitting.

Has anyone added a bulkhead fitting to a stock tank for a return?

I am considering a pass through fitting, which will allow me to run a return for EFI, however, it is an in-cab tank on my F100 so looking for something that I know will seal well on stock flat surface, standard sheet metal tank. 

Many of you guys want me to ditch the in cab tank, I hear ya... but no plan to at all, not even an option as I am trying to keep it as factory stock as possible.

This is what I did on mine.

I added a 2nd sender hole with a bulkhead fitting/ On bottom pickup I used one of the new Holley HydraMat fuel socks.
I also used bulkhead on the return.
