What brand of fuel pump is best?
Best Fuel Pumps Reviews & Recommendations 2021
Which is more reliable electric or mechanical fuel pump?
Usually, a mechanical pump is preferred over an “aftermarket” electric fuel pump. They tend to be more reliable. via
What size fuel pump do I need for 400hp?
Making the Choice
|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 much HP does it take to upgrade a fuel pump?
As horsepower increases so does the volume of fuel required to support that power. 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). via
Who makes fuel pumps for GM?

When should I use an electric fuel pump? (video)
Are big block and small block Chevy fuel pumps the same?
BB and SB pumps have a slightly different arm size and configuration. via
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. via

How much horsepower will a 340LPH fuel pump support?
The AEM 340LPH High Flow In-Tank Fuel Pump (PN 50-1000) flows 340 lph (84 gph) at 40 PSI and is capable of supporting over 1,000 HP at 43 PSI. via
Do bigger fuel injectors increase horsepower?
The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors. via
What happens if I put 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. via
What psi should a high pressure fuel pump be?
Typically, a high-pressure GDI pump creates about 2,000 psi. The sensor and the PCM help regulate the pressure to keep the fuel pressure at an ideal level for the engine in real time. via
Who makes Acdelco fuel pumps?
They are one in the same. All delco fuel pumps are made by delphi. via
Where are precision fuel pumps made?
Precision manufactures fuel pumps for Chevrolet, Ford, Toyota, Honda, Dodge, Subaru, Nissan & more vehicles. Each replacement fuel pump is manufactured in a plant in the United States that is TS 16949 certified, the latest in OE quality certification. via
Does it matter what fuel pump I use?
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. via
What is the most common fuel pump used in carbureted applications?
Prior to the widespread adoption of electronic fuel injection, most carbureted automobile engines used mechanical fuel pumps to transfer fuel from the fuel tank into the fuel bowls of the carburetor. The two most widely used fuel feed pumps are diaphragm and plunger-type mechanical pumps. via
Does fuel pump affect performance?
A failing/failed fuel pump will cause major performance and drivability issues with your vehicle. If your fuel to air ratio is off and the cylinders aren't getting enough fuel, then the pistons aren't firing and your engine is struggling to move the vehicle forward. via
Who makes Ford fuel pumps?
Ford/Motorcraft is the best overall, but a pump by Delphi will work fine (Delphi is the supplier for MC/Ford fuel pumps). That will save you about 1/2 the MC priced pump. via
Should an electric fuel pump run all the time?
The fuel pump runs while the engine is running, but it also runs when the key is turned on. So, does that mean that a fuel pump should run continuously? The answer to this question is no. A fuel pump should not run continuously. via
Does an electric fuel pump need a regulator?
Most lever style mechanical fuel pumps don't require a regulator and some electric fuel pumps even have the regulator built right into them, and eliminating the need to purchase an external unit. via
Can you replace a mechanical fuel pump with electric?
You have two options: 1. Leave the mechanical pump in place and put an electric one by the tank: You can do this if you want to keep your mechanical fuel pump as a backup in case your electric fuel pump gives out. This is arguably unnecessary because electric fuel pumps are designed to last a long time. via
Are all SBC mechanical fuel pumps the same?
The main diff is the thread size and location of the inlet/outlet ports. The mounting side is all the same. For normal stock engines all will work. via
How much fuel pressure is needed for a carburetor?
Controlling Fuel Pressure Settings
Fuel pressure should be set between 6 and 8 psi for a gasoline carburetor. An alcohol carburetor is a different animal with very different requirements. The Alky carburetor will require 4 to 5 psi at idle and 9 to 12 psi at wide open throttle. via
How do I choose a mechanical fuel pump?
When selecting a mechanical pump we need to consider the RPM at which the pump will operate and the specific target RPM for Peak Torque and Peak HP for the engine. Typically the mechanical pumps are operated at ½ crankshaft speed. via
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. via
How many psi is Walbro 255?
Description. The Walbro 255 liter per hour (LPH) high pressure (HP) fuel pump is the most popular in-tank fuel pump upgrade for the NSX. The pump flows 255 LPH of fuel at a base pressure of 43.5 PSI at 13.5 volts (an increase of approximately 65% over the factory pump). via
Are Aeromotive fuel pumps good?
Aeromotive fuel pumps are extremely efficient by design, allowing them to create high pressure on the outlet and high vacuum on the inlet side (if restricted). via
How many amps does an Aeromotive fuel pump draw?
Two pumps draw 30 amps, 3 pumps 45 amps. As pressures go higher, so goes current draw, with a peak of 19 amps per pump at 90 PSI pressure. via
Who makes Walbro carburetors?
Tokyo, Japan – Global alternative asset manager The Carlyle Group (NASDAQ: CG) today announced that it has acquired 100% of the outstanding shares of Walbro Engine Management, a global small engine parts manufacturer, from Sun Capital Partners. via
How can I make my carbureted engine faster?
You need more throttle open, because the hotter the throttle the better the air flow through the carburetor, and the more fuel it goes into. With more fuel flowing and air flowing in, the engine goes faster, which releases more energy. via
What happens if you put bigger injectors on a stock motor?
If you throw in bigger injectors it will hold that injector open for the same amount of time as the smaller injectors and it will dump TONS of fuel in. via
Can a fuel pump be adjusted?
Should the fuel pump timing be required to be changed, then the shims fitted underneath the fuel pump would be changed. If shims are added the fuel pump will inject later, and visa versa for removing the shims. via
When should you upgrade fuel injectors?
But once the engine begins to process an increased amount of air (either by adding boost or NOS or grossly changing the engine's displacement), the fuel injectors won't be able to flow enough fuel to keep the engine from running lean. This is when one should consider upgrading their fuel delivery system. via
