Jerzy the first time was  when it was new it wouldn't pump enough fuel to keep the engine running in a hard pull so I to take it off and send it back to the factory to have the pressure spring changed. Fass was good about fixing it.  Matter a fact they even sent 2 extra pressure springs back with the unit that had different pressure settings in case the one they put in wasn't enough.
