Unlimited inverted fuel supply possible?

[SneakyBastd]

I want to do sustained inverted formation flying, but all planes have quite limited inverted time before the engines flame out. Realistic, but annoying.

 

I know the virtual aerobatic team aircraft mods have inverted fuel pumps - but those are not available to the public.

 

Is there any way to replicate inverted fuel pumps? If it matters, my priority is F15C, FC3 planes, A10C. But ideally it would just be a global setting to all aircraft: "no longer check inverted time".

 

Thankyou!
