Help with pit stops

[neverender158]

So here is what is going on. I have a button mapped on my wheel for the LCD menu, so this button will scroll through all the menus like wheel temp, timing, pit stops and so on. So when I get to the pit stop menu I see fuel, which defaults to 9.2, tires, wing and some other things.  I have the D-pad on my wheel setup to go up and down in that menu, and then left or right to change anything within the pit stop menu.  I was testing this out last night and made a pit stop, stopped where my pit crew was and they changed the tires but didn't add any fuel. Here are my questions:
1)Do I need to kill the engine for the fuel to be added?
2)When doing the pit stop I see the timer running, do I go when the timer stops, because the pit crew member never raised the stop sign.
3)Where do I see fuel consumption in the HUD? I went through all the LCD menu's and drove a few laps but never could see the fuel level in my car. I thought it was on the LCD with the tire temps but that fuel never changed from 10 no matter how many laps I did.
I think that covers it for now.
Thanks

1) No need to kill the engine. They will fuel up regardless.

2) It will hold you in the pits until work is complete. Timer stops = time to go.

3) On the game tach, there are 2 numbers (in green) that pertain to fuel. gallons(liters if metric)/laps remaining

Make sure you're settings aren't set up for unlimited fuel (may default to it if running on the easiest difficulty setting). If fuel usage is turned off, you will never burn any, therefore will never need to add any in the pits.

Some comments:

1) In one of our mods (Enduracers) you will want to turn off the engine for long service times (esp. if there is damage to repair) because the engine will overheat. That is the only mod so far that does that.

2) I keep 25-50% throttle as the timer gets close and the tires will bite when you are released.

3) On some tracks the estimated laps of fuel is calculated wrong (I just recently learned why!) and will display wrong in the garage and maybe in the LCD Helios is talking about. You should always double-check fuel usage during practice/warmup.
