Fuel Pressure Regulator for Z4M
Hi,
I'm building Z4M for the track. What are my options to upgrade the Fuel Pressure Regulator of my car? (I have WALBRO HELLCAT 525LPH fuel pump) |

Well you could go back to what the E46 M3 came with.
Our Z4M's come with a farty little plastic regulator buried in the gas tank.

Interesting... is the Hellcat pump a direct replacement for our OEM pump?
