sounds like a very nice start on the build, just need a little more info here...
you are planning to going EFI right?
if thats the case you will ALOT more than just a fuel sending unit, Your old carburetor’s fuel system was a returnless system that ran at only about 5-6psi, the EFI system utilizes a return line and operates at a much higher psi. The fuel hose from your carb’s fuel system isn’t rated for the fuel pressure associated with the EFI fuel system, so it must be replaced.
here is great site i used in my swap (here
) has everything you need and can take you step by step, be safe
