Fueling Your LS Swap: A Buying Guide
Swapping an LS engine into your car is awesome! But, you need to make sure the fuel system can keep up. An in-tank fuel pump is a key part of this. This guide helps you pick the right one for your LS swap.
Key Features to Look For
You need a fuel pump that can handle the job. Here are some important things to look for:
- Flow Rate: This tells you how much fuel the pump can move. LS engines need a good flow rate, usually measured in gallons per hour (GPH). Check your engine’s specs to pick the right GPH.
- Pressure: Fuel pressure is also key. Your LS engine needs a certain pressure to run right. Make sure the pump can provide the correct pressure, measured in pounds per square inch (PSI).
- Compatibility: Does the pump fit your fuel tank? Some pumps are universal, while others are made for specific tanks.
- Fuel Types: Some pumps work with gasoline, ethanol, or both. Figure out what kind of fuel you plan to use.
- Wiring: Look for pumps that come with all the wiring and connectors you need. This makes installation easier.
Important Materials
The materials used to make the fuel pump matter. They affect how long the pump lasts.
- Pump Body: Look for pumps with a strong body. Metal like stainless steel is a good choice.
- Impeller: The impeller moves the fuel. It should be made of a durable material.
- Fuel Lines: The fuel lines should be made of a material that can handle fuel and pressure.
- Seals: Good seals help prevent leaks.
Factors That Improve or Reduce Quality
Some things can make a fuel pump better or worse.
- Brand Reputation: Buy from a well-known brand with a good reputation. They usually make quality products.
- Reviews: Read reviews from other people who have used the pump. This helps you see if it works well.
- Warranty: A good warranty shows the manufacturer believes in its product.
- Construction: Pumps with good construction last longer. Look for pumps made with care.
- Price: Cheap pumps might not last. But, the most expensive isn’t always the best.
