Pilot reports a low fuel pressure alert appeared on his mfd/EFIS display while flying his zenith CH701 amateur build experimental aircraft with a rotax 912 engine type. A newer designed engine fuel pump that was previously installed to comply with service bulletin (south/B) sb-912-063UL had failed. Pilot landed on a model airplane strip.

Narrative:
Approximately seven miles south of ZZZ; a low fuel pressure alert was given by the aircraft mfd\EFIS. Initial trouble shooting was performed by switching fuel selection. Engine RPM reduced; followed by reduced engine noise and then a surge. ATC was contacted initally with an urgent situation. A landing location was selected. As the engine struggled more; the call was changed with a mayday. Under reduced power; a landing without incident was performed at a radio control (rc) model airplane landing strip; five miles south of ZZZ. No injuries or damages to the plane or the property occurred. A mechanic was called and it was determined that the rotax uls fuel pump had failed. It was replaced in field. After testing; the aircraft was flown off the rc field and returned to ZZZ.
