Fuel pump flow rates

wobbler · 3/17/13, 3:07 AM

I trying to compare fuel rates with different brand pumps. Does anyone know what the flow rates are for different Waterman pumps as compared to a DSR pump or Hilborn pump?

Been trying good old google but it has let me down this time around

Depends on the size and the calibration effiency of the pumps. To be sure you need to have pumps checked on a flow bench. Not absolute truth here but a DSR 0 & a Hilborn 0 & a 400 waterman are somewhat close. A 450 waterman is close to both a 1/2 DSR & 1/2 Hilborn. A 500 waterman is close to a #1 Hilborn & #1 DSR . Like I said they are close but without flow bench data you risk engine damage or at least running less than optimal.
