Hey guys an gals, I believe there are two fuel pumps on my '05' M6, one operates up to 400hp at something like 3.8-4.5 bar and one that operates in 'M' mode at 6.something bar. My question is, I get a fuel pressure fault at high RPM 3rd gear (2788), which indicates that the 'M' mode pump is getting a little long in the tooth. If I remove the rear seat, which side of the tank is the secondary pump? UK car so drivers side is on the right ;-)

They are in one unit, on the right side of the tank.

Ok, so ifvu replace the pump that should be both operations?
