    Keep doing things the way you are. Your fuel pump loves you for it.

    X2, it will keep you from burning up the fuel pump. My ECSB diesel reads the same way yours does. On a trip i can drive about 75 miles after the fuel light comes on with no worries of running out of fuel. My RCLB diesel on the other hand has the larger tank and when that fuel light comes on you best be near a station.

    You don't wanna to find out. You overheat fuel pump and melt wiring. Don't be cheap and keep tank full instead run to E.

    X2 plus the fact that the more empty any tank is the more room there is for condensation to enter.

    Short bed, little tank.

    I have 04 2500HD reg cab with a 34 gallon tank also. I did not know the crew cabs and ext cabs had smaller tanks. Learn something new everyday.

    It's not the cab style, it's the bed length.........

    Do the 1500s have the same size tank if they have a crew cab? I know on the 1500 if you have crew cab you have a shorter bed cause its on 1500 frame and 6 foot bed is to long
