FyI, if you install gravity feed aux tank in you bed the ECM could set a trouble code/check engine light on some newer trucks. If the gravity feed aux tank keeps your main tank full all the time the ECM doesn't see the fuel level in your main tank decreasing over a certain amount of time and might think something is wrong with your level sensor and set a code..
