If you defeat the solenoid, how will you shut the engine off? That question must be answered first.

An upstream valve will starve the pump and not shut off well. You would have to re-design the pump solenoid to shut off on the application of power, like with a push button, so once the engine is off, you can release it to not draw on your battery.

Seems like a lot of work to save less than 30 watts. Defeat your daytime headlights and save more than that.
