Electric fuel pumps come in three basic types. As long as a fuel pump provides the Flow Rate your engine needs at the pressure your Fuel Injected or Carbureted system requires, it will work just fine . It is just a matter of deciding which one works best for your installation.
Are fuel pumps interchangeable?
In a word, no . A pump from a return-less car has a fuel pump driver module that controls pressure by rapidly turning power on/off. The pump runs all of the time. ...
Can I use a universal fuel pump?
There are fuel pumps for universal use . ... as a replacement for mechanical fuel pumps where the original pump is no longer available (old/young-timers)
Are all fuel pumps the same?
Every pump has a different flow volume at a given pressure. Because of this it is important to look at a flow chart of whatever pump you decide to buy. As free flow, or even flow at a given pressure is only part of the equation.
Can you replace an in tank fuel pump with an inline fuel pump?
Introduction: How to Convert Any in Tank Electric Fuel Pump to an External Inline Pump. This video shows how an in-tank electric fuel / diesel pump can be modified to keep the existing fuel gage / sender unit and remove the faulty intank pump, replacing it with an easy accessible in-line fuel pump.
How much HP can a mechanical fuel pump support?
Although a good mechanical fuel pump can feed your engine for up to 400 horsepower , have an electric fuel pump can be added insurance. Most carbureted systems up to this horsepower range do not use a return line. Once you get above 450 horsepower, you might want to think about a return-style fuel system.
Can a fuel pump be too powerful?
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. When the pressure is only a little over the required amount, your vehicle may sputter when you first accelerate from a stopped position.
How expensive is it to replace a fuel pump?
How Much Does Fuel Pump Replacement Cost? The average cost for a fuel pump replacement is between $220 and $1,062 depending on vehicle and age. Labor costs are estimated between $124 and $260, while parts are priced between $95 and $854. Estimates do not include taxes and fees.
Where should I place my external fuel pump?
To avoid vapor lock, the fuel pump should not be mounted in or around the engine compartment, near exhaust system components or any area that may exceed 140 degrees farenheit or 65 degrees Celsius. 5. Mounting of the fuel pump should be directly to the frame , when possible, to ensure a good ground.
How do you install a universal tank fuel pump?
Cover the hole with a block-off plate gasket and sealer. Mount the electric fuel pump near the gas tank and connect it to the fuel line. Install a filter next to the electric fuel pump. Wire the electric fuel pump to the ignition switch.
How do you inline a fuel pump?
The basic way your modern electrical fuel pump works is by utilizing a DC motor in the pump assembly which draws in the fuel sitting in your gas tank . From there, it sends it up the fuel line and into the fuel rail where it can be injected into a cylinder. It then mixes with air and a spark to create combustion.
How many GPH is a 700 hp?
Theoretically, the mechanical pump could provide the (approx) 60 gallons per hour that the engine would need, using the formula of 1/2 lb of fuel per horsepower per hour. That’s if you used a quality mechanical pump and not a stocker. So, 700 x . 5 = 350 gal .
How much is a fuel pump for 800 hp?
| Fuel Pump Free Flow Carbureted Engine Fuel Injected w/ Power Adder | 50 gph/190 lph 600 hp 400 hp | 67 gph/255 lph 750 hp 500 hp | 90 gph/340 lph 1000 hp 600 hp | 125 gph /470 lph 1300 hp 800 hp |

How do I know what size fuel pump I need?
- 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. ...
- 250 lbs./hr. ÷ 1.6 = 156.25 lph. You need the minimum flow rate at your fuel system’s operating pressure.
What are the symptoms of low fuel pressure?
Low fuel pressure can lead to engine misfires, low acceleration, rough idles, and engine stalls . If your check engine light is on and your car has been stalling out, you may have a fuel pump failure.
How do I know if my high pressure fuel pump is bad?
- Delayed start of the engine.
- Hesitation or sputtering in acceleration between 2000 RPM to 4000 RPM.
- High engine temperatures.
- Vehicle stalling due to exertion or temperature.
- Fuel pressure gauge reading low measurements.
- Poor gas mileage.
