E-pump inlet pressure

The W210 has a mechanical lift pump on the side of the E pump. The spring driven piston provides a max of ~14psi, if I remember correctly. The overpressure valve on these pumps has internals that are made of plastic. They warp and fail, letting the pressure in the galley drop. I replaced the valve with a .5mm orifice, leaving the pressure regulation to the lift pump. That has worked nicely for the last 100K miles.
