This spec doesn't apply to the car you selected.
Not yet checked against the factory manual for your car's year. It's verified in the 2003 Mazda MX-5 Miata Workshop Manual (electronic manual capture); later manuals may differ.
More than 50 psi (343 kPa; 3.5 kgf/cm²) after 5 minMore than 343 kPa {3.5 kgf/cm², 50 psi} after 5 min
Factory manualTaken from a Mazda factory workshop manual, with page citation.
Procedure
Engine stopped; use the complete factory fuel-pressure test setup, PDF pp. 713–716. Operate pump with ignition ON for 10 s, switch to LOCK, then measure after 5 min. Replace pump if hold pressure is outside specification.
