Can I use the OEM Dakota fuel pump?

I really wanted to use the OEM pump, so I spun up a threaded flange on the lathe to weld onto the OEM tank. If it won't clear the trunk pan, I'll recess the tank a bit. But I realized I'd cut the threads upside down (They're triangular with a 90 degree face) and then got busy so I haven't got back to it.
