A high-performance engine needs a high-performance fuel system. Whether you’re upgrading an LS swap, building a boosted drag car, or just want more reliability, your fuel system is the backbone of it all.

1. High-Flow Fuel Pumps

The heart of the system. For NA builds, a 255LPH pump may suffice. Boosted applications might need 340LPH or dual pumps. Make sure it’s ethanol-compatible if you’re running E85.

2. Adjustable Fuel Pressure Regulators

Vital for tuning. A quality regulator ensures that your engine receives consistent fuel under different load conditions.

3. Upgraded Fuel Lines & Fittings

Old rubber lines degrade and can’t handle the pressure. Upgrade to PTFE or braided stainless lines with AN fittings to prevent leaks and support higher flow.

4. Return-Style Systems

Modern LS swaps often require return-style systems for better pressure stability. They’re more tunable and can support higher HP levels.

5. EFI-Compatible Tanks

Don’t forget the tank! Many stock tanks aren’t baffled properly or won’t accept an in-tank pump. Consider a drop-in EFI tank with integrated pump modules.
