What if that particular Z4M coupe had a fuel pump update, how are you sure that all Z4Ms come with a WALBRO 400 ?

No I have a Z4M with an ESS supercharger and i would like to know if my OEM fuel pump is a walbro 400 fuel pump because if it is, this means that my fuel pump flows a little less than a bosch 044 and i don't need to upgrade it yet

How did my question make you feel that i'm trolling?

I actually checked a spare repair kit fuel pump that i bought soem time ago to replace when i hit 75K miles.

I can actually see that the pump inside look identical to a walbro 400.
That's a BMW part number that is also used on Z4 3.0

Could it really be a walbro 400?

The Z4M must have the old version of the Walbro 400. The new walbro 400 has a much higher performance level. Radium made a test on fuel pumps and the new walbro 400 beated the competitors in all tests.
