How much HP does a fuel pump need?
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).
Which fuel pump do I need?
Making the Choice
| Fuel Pump Free Flow | Carbureted Engine | Fuel Injected Engine |
|---|---|---|
| 50 gph/190 lph | 600 hp | 500 hp |
| 67 gph/255 lph | 750 hp | 650 hp |
| 90 gph/340 lph | 1000 hp | 850 hp |
| 125 gph/470 lph | 1300 hp | 1000 hp |
How much HP can a 340 fuel pump support?

Where are AEM fuel pumps made?
China
A: All AEM Fuel Pumps are made in China.
Can a fuel pump be too powerful?
Carbureted Engines Fuel pressure to the carburetor will range from 4 psi to 7 psi, with some vehicles using higher pressure. Using the wrong fuel pump that delivers excess pressure can cause problems ranging from poor performance and lower gas mileage to flooding and carburetor damage.
Do fuel pumps add horsepower?
No, it is just one component of the system. To get more horsepower you have to get more air into the engine, more air allows you to inject more fuel, more fuel means more power, assuming you combust it optimally.
Can a fuel pump be too big?
Too big of a cam for your combination will cause a loss of low end torque and make drivability suffer. Such is the case with fuel pumps, to some degree. This causes fuel pressure to build up to the level that the regulator was designed to maintain. Eventually, all unused fuel is returned to the tank.
How do I know what size fuel pump I need?
To determine the fuel pump size for a naturally aspirated engine, take the projected horsepower and multiply it by 0.38 to determine liters per hour. If you want to convert that number to gallons, divide the answer by 3.785.
What is boost a pump?
The BOOST-A-PUMP® is your best guarantee against fuel pressure drop off. And since the BOOST-A-PUMP® is also a voltage regulator, it automatically adjusts the pre-set voltage to the pump when the accessories lower the input voltage – or even if the alternator fails!
How can you tell a fake AEM fuel pump?
The easiest way to identify counterfeit products is if it has a very low price. In many cases, pricing that is much lower than advertised prices from Authorized Dealers is an indicator that a product is counterfeit, as are special discounts that are added to significantly lower the price of a product.
What happens if my fuel pump is too big?
What happens if I put a bigger fuel pump?
An upgraded fuel pump may move so much fuel, the factory regulator cannot bleed off the pressure fast enough. This leads to higher than desired fuel pressures which means the injectors are spraying more fuel than intended. The consequence is an overly rich air to fuel ratio and a poorly running engine.
