Fuel Pressure Spec for In-Tank Fuel Pump
Hey guys,
I have a 2008 Mercedes E320 BT. Does anyone know how much pressure (psi range) the in-tank fuel pump should be pumping out if it is working properly? 60 psi? 65 psi? 75 psi? I know my pump is working and putting out 60 psi consistently (on start up and load test) but I think that might be too low and causing my P2633 DTC.
Cheers.

Don't know factory spec, but this is just priming pump, so 60 psi sounds like plenty for purpose.
Would you have rail pressure as well?
The code sounds like bad connection, aka dirty plug at the pump btw.
Get good contact cleaner and wash all the pump connections with it.

The only code from my iCarSoft MBII is 2633-000 plus a P0101 MAF code (pending). The rail pressure at idle fluctuates between 34500kpa (5000psi) to 35800kpa (5192psi) and at heavy (not wot) throttle is around 157800kpa (22886psi).
