Very nice build you have going there.
I set up my fuel sending unit very similar to yours. One suggestion though is to eliminate the "sock" on your inlet tube. With the fuel injection you will need a better filter anyway than that. With the higher pressure and return line it may become a restriction.
Also in reference to an earlier post of yours on having issues with coming up with radiator hoses.
I had similar issue on my 74 when I converted it to the Magnum accessories. (Making room for twin turbos
)
Ended up using some 1-1/2" SS pipe and bends. Turned the ends down to match hose and welded them together.
Don't want to jack your thread so just PM me if you want more info. I have a build on another site.
Mike.
