Best External Fuel Pump For LS Swaps

The most common swaps involve installing an LS engine into a vehicle that did not come with an LS from the factory. There are many reasons to do this swap, including the fact that the LS engine is more powerful and reliable than the factory engine. One of the most important parts of any LS swap is the fuel system, and the fuel pump is a critical component of that system. The stock fuel pump in an LS engine is designed for lower-powered applications and may not be able to handle the increased power of a modified LS engine. This is why it is important to choose a high-quality aftermarket fuel pump for your LS swap.

Why External Fuel Pump Ls Swap Is Necessary?

If you are planning on doing any sort of performance upgrades to your LS engine, then you will need to consider upgrading your fuel pump. The factory fuel pump in most LS engines is not designed to handle the increased demands of a performance engine. A high-performance fuel pump will ensure that your engine gets the correct amount of fuel, at the correct pressure, and at the correct time. This will help maximize power and prevent your engine from running lean and potentially damaging itself.

Benefits of External Fuel Pump Ls Swap

An external fuel pump is a great way to add extra performance and reliability to your LS engine swap. Here are some benefits of using an external fuel pump:

1. Increased Fuel Flow: An external fuel pump can flow more fuel than the stock internal pump, which means more power for your LS engine.

2. Better Fuel Pressure Regulation: By moving the regulator outside of the engine bay, you can keep your engine running cooler and avoid potential issues with overheating or vapor lock.

3. Enhanced Reliability: External pumps are generally much more reliable than stock internal pumps, especially under high-performance conditions.

Buying Guide for Best External Fuel Pump Ls Swap

There are a few things to consider when purchasing an external fuel pump for your LS swap. The first is the volume of fuel required by your engine. If you have a naturally aspirated engine, you will need/use less fuel than if you have a forced induction setup. This will help determine the appropriate size pump to purchase. The next thing to consider is the pressure requirements of your fuel system. Most LS swaps will require a high-pressure fuel system, so make sure the pump you purchase is capable of reaching the desired pressure. Another important factor is compatibility with your existing fueling components. Make sure the pump you purchase can be used with your current injectors, regulator, and other accessories. Finally, take into consideration the price and brand of the pump before making your final decision.
