Converting Fuel Pump PSI to ltrs per hour....

So I've got a fuel pump that outputs 125psi - what's this in litres per hour as I need to know before I get the car on the RR?

I've sure some of you techie types will know.

PSI and flow rates are not the same thing.
A pump might produce high psi but the flow rate could still be low.
You need to look up the manufacturer or manual if it is from a known car.

If its a Bosch pump then type whatever numbers are on the side.. it usually turns something up somewhere.

Only other way would be to run the pump for 10secs or a 1min into a measured container and then multiply that to give it in L/hr

As the others said, you need to know flow rate, and you are quoting pressure, unfortunately as much help as what colour it is!

Let us know the pump make and model, I have a spec sheet here for all bosch injection pumps, though I'll bet its a walbro if its on an uprated nissan.





Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion retro car restoration and tuning
