How much PSI does a fuel pump have?
Electric fuel pumps are normally used to supply the higher pressure demanded by the system. The required pressure can be as high as 66 psi with port injection. The pressure on the throttle body injection systems is between 9 and 18 psi.
How do I know if my fuel pump is Lph?
Fuel Pump Specs Defined
- 500 X 0.5 = 250 lbs./hr. A gallon of fuel weighs 6 lbs. To get gph divide lbs./hr. by 6.
- 250 lbs./hr. ÷ 6 = 41.67 gph. A liter of fuel weighs about 1.6 lbs. To get lph divide lbs./hr.
- 250 lbs./hr. ÷ 1.6 = 156.25 lph. You need the minimum flow rate at your fuel system’s operating pressure.
How much power does it take to run a fuel pump?
Horsepower A good estimator of volume to power is approximately 10 hp per gallon or 2.64 hp per liter. For example if your pump flows at 50 gph it should be able to support a 500 hp engine (50 x 10 = 500).
Will a fuel pump run on 10 volts?
Your fuel pump only runs at 12 volts when you turn the key to the run position – normally it runs on Battery voltage which can range from 13.5-14.5 volts.
How many volts should I get at the fuel pump?
System voltage should read 11.8 – 12.6v DC or higher with no electrical loads on the system. If voltage reads less, starting and charging system should be investigated before performing fuel system electrical testing. 1. Connect digital voltmeter to fuel pump wiring at fuel pump connector.
What is the average range of pressure for fuel pump from the tank in a fuel injection system?
Fuel Injection Engines Engines with fuel injection will normally use electric fuel pumps to supply the higher pressure demanded by the system. With port injection, the required pressure ranges from 45 psi to 66 psi. On throttle body injection (TBI) systems, the pressure is normally between 9 psi to 18 psi.
How many LPH is a 1200 hp?
To estimate flow, simply multiply 1,200 horsepower x 0.9 BSFC = 1,080 pounds of projected fuel per hour.
