Does your car come with single pump or double pump? Mine is Euro spec, so it's single external pump. That's the bosch unit that replaced. The replacement pump is longer than the original. TRE & Walbro pumps has higher flow, pressure is the same. As pressure is regulated by FPR, should be 2.5bar unless uprated.
RM406 for my new Bosch unit. Runs well, no more weird noises anymore.
