Ok I am new to the f4i I have an F3 had and F2 and last week I pick up a wrecked 2003 f4i. The front was smashed into a car. I got new gages today and when I fire it up the fuel indicators flash and then go off. I was told they come on with about a gallon left is this true? Also maybe kinda dumb I know but the clock always stays on??

 

The reserve bars should come on when there is about .9 of a gallon left, that is if all 4bars are solid. And yes the clock is always ticking...
