anyone modify stock sending unit for intank pump?

I run a fast Efi setup as well. On my a-body tank I modified it to use their external pump. But if it doesn't last I will be going to An in-tank pump. I think it would be fairly easy. Just mount the pump at the end and same original length. Then maybe add some bracing to support the pump would seem all that bad. That's really not any help but I have thought about it a little for my next time around if I need it.
