Yep, still laughing. Pishta doesn’t explain anything. Picking a fuel pump based on horsepower is like buying a cylinder head based on airflow.
There is way more to it than calculating how many pounds of fuel per hour an engine burns. That’s why an engine dyno can use a much smaller fuel pump than you can in a real car.
That Carter pump you posted wouldn’t run a decent hooking Briggs and Stratton.
