I THINK that a momentary contact kill switch would work here. Hold the switch long enough for the engine to coast to a stop, then release. Once released, the fuel pump should restart and pressurize the fuel system so everything is ready to go when bump started.
The vacuum gauge plus wheel covers helped increase summer 2015 mileage to 38.5 MPG, while summer 2016 mileage was 38.6 MPG without the wheel covers. Drove 33,021 miles 2016-2018 at 35.00 MPG.
