With a hobbs switch you will get a sudden hard surge in fuel pressure, which causes all kinds of tuning nightmares of which no one talks about or do not care that it happens.

When the fuel pressure swings wildly you get rich and lean surges that follow.

At the end of the day it is not the pump itself, it is the quality of the fittings hose and control system that sets them apart.

Never skimp on fuel system, most engine failures can be linked to lack of fuel supply.

So, as long as their is a pressure regulator in the system the rich/lean spikes wouldn't be that much of a concern?
