Supra fuel pump (Denso 195130-1020) low pressure flow rate?
I can't seem to find this info anywhere and thought maybe someone here knows it or knows where I might find it.
What is the flow rate of the ever popular Denso 195130-1020 fuel pump (Supra/RX7 Store Nippondenso/RP competition pump) at 0psi, 10psi...preferably at 13.5V? Reason I ask is because I'm trying to calculate fuel surge tank refill times using this pump as the in-tank lift pump. Generally I like to use the 10psi figure for this, but if I could find any reliable info below 40psi I could use that an extrapolate a somewhat educated guess. The only place I have seen figures for this is at www.densofuelpump.com, but I don't trust the data because it doesn't match any of the flow test charts I've seen for the same pump (even shown on the same page) for flows at 14V at 40psi+. |

The best guess I can make with the data I have is to assume a linear relationship for flow between 0psi and 45psi. Using this assumption and the data points for 35psi and 45psi (287lph and 272lph @ 13.5V respectively) here are the extrapolated low pressure flows at 13.5V. PSI | LPH 0 | 336 5 | 329 10 | 322 15 | 315 20 | 308 25 | 301 30 | 294 This is far from accurate, but I guess it will have to do. |
