As someone who has completed an LS swap on my vehicle, I cannot stress enough the importance of a fuel pump kit specifically designed for this type of engine conversion. While it may seem like an added expense or an unnecessary step, trust me when I say that it is crucial for the success and longevity of your LS swap.

First and foremost, an LS engine requires a higher fuel pressure than most other engines. This is due to the fact that they are designed to run at a higher compression ratio, which requires more fuel to achieve proper air-to-fuel ratio. Without a fuel pump kit designed for an LS engine, you run the risk of not having enough fuel pressure which can lead to poor performance, engine misfires, and even engine damage.

Additionally, most LS engines require an electronic fuel pump rather than a mechanical one. This means that in order for your LS engine to run properly, you will need a fuel pump kit that includes not only the pump itself but also all the necessary wiring and connections. Trying to piece together these components separately can be time-consuming and may result in compatibility issues.

Furthermore, a properly designed fuel pump kit will have all the necessary components to ensure proper installation and functionality. This includes things like mounting brackets, fuel lines, fittings, and filters.

My Buying Guide on Fuel Pump Kit for LS Swap

As someone who has gone through the process of swapping an LS engine into my vehicle, I know how important it is to have a reliable and efficient fuel system. The stock fuel pump in most LS engines is not powerful enough to handle the increased horsepower and demands of a swapped engine. That’s why investing in a good fuel pump kit is crucial for a successful LS swap. In this buying guide, I will share my knowledge and experience to help you make an informed decision when choosing a fuel pump kit for your LS swap.

Understanding LS Swaps and Fuel Pump Requirements

If you’re planning on doing an LS swap, chances are you already know about the benefits of this popular engine conversion. The LS engine is known for its power, reliability, and aftermarket support. However, when it comes to choosing the right fuel system for your LS swap, there are a few things you need to consider.

The first thing to understand is that most LS engines come with a returnless fuel system, which means there is no return line from the fuel rail back to the tank. This type of system requires high-pressure fuel pumps that can deliver enough flow rate to meet the demands of the engine.

Another important factor to keep in mind is that most stock LS engines have an in-tank fuel pump that may not be suitable for your swap. This type of pump can struggle with higher horsepower levels and may also require modifications to fit into your new setup. That’s why investing in a high-performance external fuel pump kit designed specifically for LS swaps is highly recommended.

Choosing the Right Fuel Pump Kit

There are many options available when it comes to choosing a fuel pump kit for your LS swap. It can be overwhelming, but here are some key factors that you should consider before making a purchase:

Type of Fuel Pump

The two main types of fuel pumps used in most LS swaps are electric inline and in-tank pumps. Electric inline pumps are mounted outside the tank and require custom mounting brackets. They provide better flow rates but may be louder compared to in-tank pumps. On the other hand, in-tank pumps are quieter but may not provide enough flow rate for high-horsepower setups.

Fuel Pressure

Fuel pressure is crucial when it comes to delivering enough fuel volume to your engine. Most stock LS engines operate at around 55-60 psi, but some performance builds may require higher pressure levels up to 80 psi or more. Make sure to choose a kit that can handle your desired fuel pressure requirements.

Fuel Compatibility

It’s important to ensure that the fuel pump kit you choose is compatible with the type of fuel you plan on using in your setup. Some kits may only be suitable for gasoline while others can handle alternative fuels like E85 or methanol.

Horsepower Rating

The horsepower rating of your chosen fuel pump kit should match or exceed the power output of your engine. It’s always better to go with a higher-rated pump than what you currently need as it allows room for future upgrades without having to replace your entire setup.

Additional Components

Aside from the main components such as the pump itself and necessary fittings, some kits may also include additional components like wiring harnesses, filters, lines, regulators, etc. These extra components can save you time and money by providing everything you need in one package.

Budget Considerations

Fuel pump kits range from affordable options under $200 up to premium kits costing over $1000 depending on brand and features included. It’s important to set a budget before starting your search so you can narrow down your options and choose what fits best within your price range without sacrificing quality or performance.

In Conclusion

An upgraded fuel pump kit is essential for any successful LS swap project as it ensures proper delivery of enough high-pressure fuel volume required by these powerful engines. By understanding your specific needs and considering all factors mentioned above before making a purchase, you’ll be able to find the perfect fit for your budget and horsepower goals.
Happy swapping!
