I have a new adjustable fpr and recently hotwired the factory pump on my 87 GN. What type of performance increase should be expected by upgrading to a Walbro? I realize that the factory pumps are only marginal, but what can I realistically expect?

Consistent volume and pressure and enough fuel to support double the horsepower of the stock setup.

...however, may result in not much hosepower improvement. But clearly the safety and support for a LOT more horsepower going forward, as Ken stated. :tup:
