There are special procedures onto a cold start, but it not concerns the fuel pressure. At every engine start, in all weather, you should use the fuel pump, if the fuel pressure under 0,5 atü (~0,5 kg/cm2) (in the E manual 0,5 atü, in the G-2 manual 0,3 atü).
Later (for example in G-2), you have electric fuel pump, but you can access the manual fuel pump through the inspection hatch underneath the forward section of the fuselage.

The gear emergency opening:
I just now tested, the manual pump helps the emergency opening in the game really. The notzug "system" is a simple cable, which releases a lock. The gear falls out with the help of the gravity if there is not oil pressure already in the cylinder. Anyway, not exist manual pump in the hydraulics system (one pump is on the engine), but has exist in the fuel system.
This is a bug then...
