Hi I am wondering will direct wiring a fuel pump to a toggle switch directly to 12 volts cause a decrease in gas mileage? I have recently done this on my 2.9 and not only does it seem like I'm getting half the gas mileage that I was before I can also clearly hear my high pressure fuel pump just underneath the driver's floorboard running the entire time it's on, EVEN over the motor running, which was not the case whatsoever before I hotwired it. Does the fuel pump relay possibly reduce amperage or voltage being sent to the fuel pump? I'm just confused at why I have such a substantial decrease in my fuel mileage when all I did was hotwire the fuel pump. Anybody has any knowledge behind this please let me know I can easily wire it back up to the inertia switch which I intend to do regardless however if this is the cause it will definitely be moved to the top of my priority list thank you
