I believe the pressure of each pulse gets higher than that. I remember testing to pump with diesel from a bottle and trying to block the output with the finger which was quite hard to do. I mean I could feel it pushing quite hard. Maybe I will redo the test and pay more attention to the result..More like 0.0145psi.
The pump moves .22ml on each stroke, so no great pressure, besides, webasto/eberspacher sell a little diaphragm type shock reducer to put in the fuel line, why would they sell that if you needed pressure pulses in the feed?
