I agree, priming is only a significant issue when the fuel is stopped at
the tank, allowing the filters and lines to empty. Modern automotive
systems have a low pressure electric pump in the tank- I was suggesting
that interrupting the power there would not be the best idea.

Careful with the idea of an injector rail and return line, gas engines have
this but diesels don't. Between the injector pump and the injectors are
separate lines to each cylinder- and no return line. (though some have
return lines before the injector pump)
