I have a 2001 Mercedes c320 and I need to know the following. On top of the fuel pump there is a pressure sensor. Does this sensor detatch or would I need to replace the entire fuel pump?

 

the whole unit will need to be replaced i believe. there are no detachable parts on the fuel pumps. there is a fuel pressure regulator built into the fuel filter.

 

Hey thanks. Can you help me with some codes? P201C, P0450, and P2010. Also, my BAS indicator light came on the same time my cruise control stopped workng. Do you think it may be a switch under the brake pedal?

 

yes good possibility

 

my check engine light is on and had the car "read" and the code p201c said i need a fuel canistor pressure sensor. The mercedes place sent mea sending unit and wont give me my money back. just wanted to make sure i needed a fuel pump to correct the problem. ur info is greatly appreciated
