For example, if you have a stock engine that makes horsepower, your equation will look like this: HP x. OnAllCylinders says: October 15, at am. Riley Smith says: December 2, at pm.

As free flow, or even flow at a given pressure is only part of the equation. Fuel pumps have different flow rates at different voltages.

As voltage increases so does the speed of the fuel pump which will increase the flow of a pump at any given pressure. Because of this it is good practice to see how a pump is rated at a given voltage. Most cars will produce about However, if your alternator does not produce Now that you understand the three main factors that you should consider when selecting a fuel pump you can put all that information together and get a good idea of how much horsepower a given fuel pump can supply for a specific setup.

All that you need is a fuel flow chart of the pump that you are considering. For example take a look at our GPA-4 fuel pump assembly flow chart. Now lets assume that your engine requires 60 psi and your fuel pump will be supplied with As you look at the chart you can see that at 60 psi and If you use that same pump on a carbureted engine the pressure required for most carburetors is under 10 psi.

Again assuming 10 psi and As you can see from the two examples above the pressure required for your engine drastically changes the amount of flow a pump can produce which in turn affects the amount of horsepower a given pump can support.

Keep in mind that it is always a good idea to estimate conservatively when selecting a pump. Figure your horsepower on the high side so that you have a large enough pump for your system.

If your pump is larger than what your system requires the excess fuel is simply returned back to the tank through the fuel return line.
