I replaced the original pump with a walbro 450.
After a few days a connecting tube was broken (part Numbers 13907833397)
If you do not have gas pressure check the pump connection pipe.

Z4M has the tank internal pressure regulator and one line to the engine. M3E46 instead has two lines and pressure regulator on the injection pipe.
