The pressure from the fuel pump is needed to get the fuel into the
carburettor.  Once the fuel is in the float bowl, the engine will be able to
use it whatever the boost pressure until the float bowl runs dry.

Hi Ron,

You are asking a carburetion question.

When you stop the fuel pump the pressure across the carburettor fuel 

input valve goes from positive (5 psi I believe)  to negative actual 

boost pressure I would think.

I would guess that the only way to keep the engine running is by 

removing all boost and even then you would have extremely low fuel pressure.

All in all I would not like to count on it working.

Jan de Jong
