Unhappy 02 C240 - Code P0453 Evap Emission Control System Pressure Sensor High Input

Hey guys. My fuel pump just went out and I replaced it myself but now the CEL is on. Went to Advance and borrowed the code reader and this is the code it threw out - Code P0453 - Evap Emission Control System Pressure Sensor High Input. Anybody ever had that one? Any idea of where to start?

Thanks,
Scott

Check all pipework you disturbed when changing pump - This is most likely source of the problem.
Check tank breather pipe from both tanks to filler neck to ensure that you did not kink or block it.
Check pipework to charcoal canister for kinks or blockage.
Finally check that you don't have a stuck purge valve up front in the engine compartment.
