Fuel systems

The fuel system is a crucial part of the car’s overall setup when fuel needs to be delivered safely, consistently and in the correct amount to the engine. In tuning, motorsport and conversions, the original fuel system is often not enough, especially if the car is getting more horsepower, a larger turbo, different engine management or is going to be used under heavier load. That is why many choose to upgrade to a fuel system that better matches the car’s power target and the specific project.

At Qualitec, you will find an exciting range of parts for fuel systems for street cars, race cars, drift cars and more serious motorsport projects. A well-functioning fuel system is important because it helps ensure the correct fuel supply to the engine, even when load increases. This provides a better foundation for stable engine operation, more precise tuning and greater safety in a performance setup where lack of fuel can cause major problems.

In this category, you will find fuel pumps, fuel pressure regulators, catch tanks, fuel rails, fuel hoses, AN fittings, filters, adapters and other accessories for building or upgrading fuel systems. Whether you are working with an in-tank or external fuel pump, an EFI setup, motorsport or a custom-built solution, it is important to choose components that match correctly.

An upgraded fuel system is often used when the original solution can no longer keep up. This may be with higher power output, larger injectors, an ethanol or E85 setup, motorsport use or projects where better control of fuel pressure and a more reliable fuel supply are required. With the right components, it becomes easier to build a fuel system that matches both the engine, the application and future upgrades.

It is important to know the target for how much power you want the system to be able to support with stable and sufficient fuel delivery. It is also important to consider whether you will be driving fast through corners, where the fuel can be forced to one side of the fuel tank and cannot be picked up properly. If you are going to use the car for motorsport, we therefore recommend installing a surge tank.
