2005 C240 4Matic fuel pressure sensor

Tracking down the elusive P0446 one of the things mentioned in previous threads was to look at the fuel pressure sensor… I ordered what is supposed to be an exact replacement for my car but nothing is matching up… am I missing something???

What makes you think the cause of your code is the low pressure fuel pump? That is a pretty general code.
