Some variables here that need establishing.
We have an IO-360 parallel valve motor with Silverhawk injection. It doesn't have a return line, therefore after landing when everything is warm, you need to pay attention if you start - say - after fuelling.
Throttle 1/4" open, mixture lean, no pumps - crank until it fires then smoothly advance the mixture and it should pick up fine.
It may run like a rough old jalopy though because there is vapor around and it just needs ingesting. A blip with the pump may help, but it isn't recirculating anything, it is just pumping into the motor.
It is normal for the motor to run rough - surging and dying for a couple of minutes, particularly on a hot day. Once you open up to significant fuel flow on take off, it will be fine.
If you Airflow Performance, then there are differences and you need to refer to their operating instructions.
Hope that helps.
