Not much more than 13 GPH.

Of course if I upgrade to fuel injection and tuned intake that should increase.

Can the explanation be that the sudden change in velocity/pressure caused by such a restriction cause the fuel to boil (evaporate)?

think that good engineering practice is to have a supply 
capacity that exceeded that flow by about 20%.

That's right. Oddly enough it will gravity flow about 17 GPH through 
that hole.

The inlet hole to the flow sensor turbine is only 1/8" !
   

        

Finn, are you saying that all the fuel going to the engine has to be sucked
through an 1/8" hole? If that's the case, this could be your problem?
