30 Amp Fuel Pump Wiring Kit

The AEROMOTIVE 30 Amp Fuel Pump Wiring Kit (AFS16301) is a complete, purpose-built harness system designed for builders upgrading to high-flow fuel pump systems or converting fuel delivery on street rods, race cars, and modified daily drivers. This kit eliminates the guesswork of running adequate amperage to modern fuel pumps by delivering a factory-quality installation with all necessary components included. Whether you're installing an aftermarket fuel pump on a classic engine swap or upgrading fuel system capacity for forced induction, this wiring kit provides the electrical backbone your fuel system demands.

Built around a robust 30-amp circuit capacity, this fuel pump wiring harness includes a dedicated relay, heavy-gauge wire, connectors, and cable ties—everything required for a professional-grade installation without hunting down separate components. The relay design isolates fuel pump load from your vehicle's ignition circuit, protecting factory wiring and battery connections while ensuring stable voltage delivery under peak demand. Proper fuel pump wiring prevents voltage drop that starves injectors of pressure during acceleration, reduces parasitic draw on the alternator, and eliminates the risk of melting factory harnesses when upgrading to higher-capacity pumps. The 30-amp rating accommodates dual fuel pumps, high-pressure systems, and pump configurations up to approximately 255 liters per hour—ideal for turbocharged, supercharged, or nitrous-equipped builds.

Serious fuel system upgrades demand electrical infrastructure that matches pump capability, and this kit is engineered for builders who refuse compromise. Installation works across universal applications—classic Chevy restorations, LS swaps, modern fuel-injected conversions, and dedicated race car projects all benefit from the safety and reliability this harness delivers. The included connectors and relay integrate seamlessly with factory grounds and battery connections, while the relay mounting flexibility accommodates engine bays of any layout. Mechanics and enthusiasts upgrading from mechanical pumps to electric units, or stepping up pump displacement for modified engines, will find this kit eliminates potential gremlins and ensures fuel system voltage remains stable under sustained full-throttle operation.
