High throttle miss

You can wind it up a bit more, or fit a slightly heavier spring.

In a bypass regulator setup, the excess is returned to the tank, and the pump bypass will never operate operate while spring loaded.

Food for thought?

I disagree with this statement: The factory internal bypass is way higher than any normal pressure setting for carbs

Only my pump is set at 7 pounds. It can pump out more but the pumps regulator sets the pressure at 7 pounds at the pump's output.

Now you take that 7 pounds, push it thru a 40 micron filter, along 8 feet of 3/8" hose plus connectors to the pressure regulator. The pressure drop is around 3 pounds, leaving me with maybe 4 pounds when at max flow.

If I had bought the 140 which is pre-set at 14, this would work since the pump's internal bypass would not get activated. But I don't have that pump.

So, I need to block my pump's bypass so it will go above the factories setting of 7, so I can actually get my desired 6.5 at the carb - letting the fuel pressure regulator control the final pressure.
