As a car enthusiast who has done multiple LS engine swaps, I can confidently say that an inline fuel pump is a crucial component for the success of the project. The LS engine, although known for its power and reliability, requires a higher fuel pressure than most stock engines. This is where an inline fuel pump comes in to play.

The stock fuel pump in most vehicles is not powerful enough to supply the necessary fuel pressure for an LS engine. This can lead to lean conditions, which can result in engine damage or even failure. By adding an inline fuel pump, you ensure that your LS engine is receiving the correct amount of fuel at all times, thus avoiding any potential issues.

Moreover, an inline fuel pump also offers more flexibility when it comes to choosing the location of your fuel tank. In some LS swap projects, the original location of the fuel tank may not be compatible with the new engine setup. In such cases, having an inline fuel pump allows you to place the tank in a different location while still maintaining proper fuel delivery.

Another advantage of using an inline fuel pump is its ease of installation. Unlike in-tank pumps that require dropping the entire gas tank for installation, an inline pump can be easily mounted on the frame rail or near the tank with minimal effort. This makes
