also i agree the fuel setup is a nice design .. as id expect on and ///m car to be honest...

I would bet 1 million dollars it's a Bosch .Just bc the cap looks similar does not mean the pump is a Walbro . Not to mention people who run more than 550 hp have had to upgrade the pump due to inadequate fueling , Including ESS. The Walbro 400 would be plenty lol . BMW has never used anything besides a Bosch pump in any of their cars . Just bc one persons said it on a forum post DOES NOT make it true .
