Electric Fuel Pumps In Mini Trucks & Their Advantages

Modern engines in mini trucks use fuel injection systems. This current sophisticated system relies on an electric fuel pump to function. The electric fuel pumps drive fuel to the injectors at a given pressure. After receiving the fuel, the injectors spray it into the combustion chamber. This is the mechanism under which a petrol direct injection works. 

The electric fuel pump does the role of supplying the engine with the required quantity of fuel despite the temperature of the engine. This kind of pump will automatically switch on once you ignite the engine. This capability makes the electric fuel pump the best to start a mini truck that has stayed for long at the parking yard. Let us have a look at the advantages and disadvantages of the electric fuel pump.

Advantages of an Electric Fuel Pumps

These pumps can cover 100,000 miles on service. They will give you a long time of service. Your mini truck’s general health must be good for them to reach this mileage.

The electrical fuel pump is fitted with a safety feature called the inertia switch. This switch is sensitive to body rolls. It automatically switches off the electric fuel pump when it detects an accident. Switching the pump will cut fuel supply to the engine, thereby stopping the combustion process in the combustion chamber.

It has the Electric Management Unit, which controls the activities of the electric fuel pump. This unit can switch on or off the pump when the engine is running and helps to regulate and ensure constant fuel supply into the combustion chambers.

The electric fuel pumps operate nonstop once they are on. They are installed within the fuel tank to cool and protect them from fire. When functioning, the fuel pump is prone to fire or fuel leaks. Inside, the fuel tank is safer from such eventualities.

They supply fuel under high pressure, which modern fuel-injected engines require. The mechanical fuel pumps cannot generate adequate pressure to deliver fuel to the injectors.

Disadvantages of Electric Fuel Pump

Replacing the electric fuel pump mounted inside the fuel tank is very expensive and takes time. If your pump is located in the fuel tank, in case it requires a replacement, be sure to spend more cash and time on replacing it.

The electric fuel pump might fail without giving you a clear warning. In this case, you might keep using the mini truck and end up causing more damage to other engine parts.

If your mini truck develops ECU or electric problems, the electric fuel pump will not function because it depends on the ECU.

Conclusion

The electric pump is all you need for your mini truck to gain more power. The fuel-injected mini truck is robust compared to mini trucks with carburetors. It is because their combustion chamber receives a regulated fuel constantly under high pressure. Despite the few disadvantages of the electric fuel pump, they remain popular in modern cars. Therefore you will not miss the point if you decide to replace your fuel pump.

Daihatsu Hijet Fuel Pump Conversion

Daihatsu Hijet is a minitruck with incredible performance despite its small engine. It has either a carburetor or a fuel-injected engine. Both of them receive fuel through a fuel pump. The engine has fuel pumps that feed fuel to it through the injectors or the carburetor. There are two types of the fuel pump in the market- mechanical and electric fuel pumps. In this guide, we will focus on Daihatsu Hijet fuel pump conversion.

A mechanical fuel pump applies a vacuum to transport fuel to the carburetor. From the carburetor, the fuel gets into the combustion chamber. Engines using this mechanism are prone to flooding and other fuel pump-related issues. The electric fuel pump relies on the ECU that controls it as it facilitates fuel movement from the tank to the injectors. The fuel injection system demands fuel under high pressure, and the electric pumps have this capability. Initially, vehicles relied on the mechanical fuel pump, but as technology advanced, automakers invented the electric fuel pumps, which were better.

Advantages of Electric Fuel Pumps

You can install the electric pump in the fuel tank. Submerging it in the fuel cannot destroy but cools it and exposes it less to fire accidents.

The ECU system controlling the electric pump makes them safer as the ECU controls when it should be on or off. In case of an accident, the ECU switches it to cut the fuel supply to the engine.

The electric pumps are durable and can serve you for 100,000 miles.

How to Do Daihatsu Hijet Fuel Pump Conversion

You can acquire and install an electric fuel pump on your Daihatsu Hijet if it uses the mechanical pump. These steps will help you perform the procedure.

  1. Open the battery compartment, remove the negative cable, and disconnect the fuel cap from the tank. Doing this will cut the fuel supply and reduce the pressure in the fuel tubes. You can step on the accelerator to remove further pressure.
  2. The fuel tubes connect the mechanical pump and the tank. Remove the clamps that attach these tubes to the mechanical pump. When doing this, have a clean container to tap the fuel from the tubes. Disconnect the tubes attaching the mechanical pump to the carburetor or the fuel injectors. At this point, you can extract the mechanical pump.
  3. Fix the new electric pump, not exposing it to any damage or heat from the engine. Use the bracket and the sheet screw metal to hold the pump firmly.
  4. The electric pump has a black and red wire. Attach the black one to the screw, which will ground it. Use a masking tape to combine the red and the #12 wires and attach them to the ignition fuse. This will put the electric pump on upon the ignition of the Daihatsu Hijet.
  5. Disconnect the old fuel tubes from the tank and the carburetor or fuel injectors. Connect the new fuel tubes from the electric pump.

Conclusion

The above procedure will help you to install a reliable electric fuel pump. It is necessary to perform this under the guidance of an experienced mechanic.

Changing Mazda Scrum Fuel Pump

It is fantastic to own a Mazda Scrum. The demands of this mini truck are minimal, yet it will offer you the best services. This mini truck consumes significantly less fuel, and the cost of servicing it is lower than a standard pickup truck. Owning this mini truck requires hacks that will help you take care of it. More important is understanding your Mini truck, how it behaves when in good condition, and when it requires a mechanical check-up. Let us focus on the fuel pump and particularly changing Mazda Scrum fuel pump

How Well Do You Know The Fuel Pump?

The engine of a Mazda Scrum has a displacement of 658cc. This small displacement makes it consume significantly less fuel. But how does the fuel reach the engine? Between the fuel tank and the engine are the fuel tubes, the channels fuel follows to move from the fuel tank to the engine fuel injectors. For fuel to travel to the engine injectors, there has to exist some pressure for this. The fuel pump provides the pressure and, apart from this, promotes a continuous flow of fuel to the engine injectors.

Occasionally, the fuel pump might become faulty. You will realize this when your Mazda scrum becomes too weak to go up a hill or to tow loads, when the engine goes off unceremoniously and when you experience difficulty starting the engine. These signs are related to a malfunctioning fuel pump.

Symptoms of a Faulty Fuel Pump in a Mini Truck

The internal combustion of a mini truck works when it receives adequate fuel. Every vehicle has a fuel tank, either one or more, to store fuel. The fuel pump generates the energy to move fuel from the fuel tank to the Engine’s combustion chamber. This fuel gets into the cylinders through fuel injectors or the carburetor. The Engine needs adequate fuel pressure for it to function as it should. When the fuel pressure is high, the Engine might flood, and when it is low, your engine is likely to misfire. The fuel pump controls the pressure. In this guide, we will look at the symptoms of a faulty fuel pump in a mini truck.

Symptoms of a Faulty Fuel Pump in a Mini Truck

If your fuel pump becomes faulty, your mini truck’s performance will reduce, and you will experience a lot of issues while driving the mini truck. When the fuel pump is not functioning correctly, the fuel-to-air mixture in the combustion chambers will not be proportional. If the fuel pump is not supplying adequate fuel, the pistons will not fire correctly, and the vehicle will experience difficulty moving. If the fuel pump is completely damaged, your mini truck will not even start. When your fuel pump is faulty, you feel the following signs

Experience Difficulty when starting

When starting your mini truck becomes difficult, or if it completely refuses to start, the fuel pump is probably faulty. If it produces the cranking sound, the Engine is not getting fuel. The fuel pump is faulty if your mini truck is cranking, but it takes time to start.

The Engine Goes Off When Driving

It feels terrible when your mini truck dies in the middle of the road. When this happens, your fuel pump does not generate adequate pressure to transfer fuel to the combustion chamber. Your mini truck will not get enough fuel and air to burn. Therefore your vehicle will stall.

Surging Engine

When your Engine surges as you drive, it receives a lot of fuel. You will note this when your mini truck picks up and drops speed without necessarily stepping on the gas pedal. A lot of fuel can result in engine flooding. 

Poor Fuel Efficiency

When your mini truck consumes too much fuel over a short distance, there are high chances of your fuel pump being faulty. A faulty fuel pump will supply too much fuel into the engine, making your mini truck less economical.

Your Engine becomes Weak as You Drive Uphill or Towing

When your mini truck goes up the hill or is loaded, its engine will strain and require more energy. The fuel pump delivers more fuel into the combustion chamber to generate more energy. If the fuel delivery into the combustion chamber is inadequate, you will feel your mini truck is getting weak when loaded or moving up the hill. 

Conclusion

It is essential to be careful and observant before and while driving your truck. Being observant will help you to determine the early signs of a faulty fuel pump. If you never replace your fuel tank in time, your engine might develop complications.
