FASTSTORM 12V Electric Fuel Pump Relay Kit — 60A Waterproof Relay, 10 AWG Heavy‑Duty Wiring

FASTSTORM's 12V Electric Fuel Pump Relay Kit is a complete, heavy‑duty relay and wiring harness that reliably routes battery power to your fuel pump while minimizing voltage drop and protecting the circuit.

This kit is built for automotive and 12V systems where a stable, high‑current feed is required. It replaces or upgrades factory relay circuits with a waterproof relay, stout gauge wiring, and a fused battery feed so your pump—or any 12V accessory—gets consistent voltage without overloading the original harness. The package includes everything needed for a tidy, straightforward install and is engineered for durability in harsh environments.

How does this relay kit prevent voltage drop and protect my fuel pump?

The harness routes battery power directly to the pump on a 10 AWG feed, which cuts resistance and avoids the typical voltage sag found in thin factory wires. A dedicated fuse and heavy relay contacts guard the circuit from overloads and short circuits, reducing the chance of electrical stress on the pump. The waterproof relay housing also keeps moisture out, preserving contact integrity over time.

• 10 AWG red battery feed minimizes voltage loss
• 60A relay provides robust switching capacity
• 30A inline fuse protects against shorts and overloads
• Waterproof relay casing resists corrosion and moisture

What comes in the box and how easy is it to install?

The kit is delivered as a ready‑to‑connect assembly with color‑coded leads and a simple wiring diagram, so you can install it with basic tools. Wires are pre-measured for common engine bay routing—long battery lead plus pump lead—reducing the need to splice or extend. Mounting hardware and a waterproof fuse holder are included to secure the components and maintain a factory‑clean look.

• Includes 60A relay, relay harness, fuse holder, 30A fuse, and mounting hardware
• Color-coded and labeled wires for quick identification
• Clear wiring diagram for step‑by‑step connection
• Long battery and pump leads for flexible routing

Will this work with my vehicle or other 12V equipment?

This relay harness is designed for universal 12V systems and fits most vehicles, trucks, ATVs, and aftermarket 12V accessories that require an externally switched power feed. It supports devices that draw under the kit's continuous ratings and is especially suited to high‑pressure or high‑current fuel pumps that benefit from direct battery power. Confirm wire routing and available mounting points before installation for best fit.

• Universal fit for most 12V automotive and light‑vehicle applications
• Suitable for pumps and accessories that match kit amperage limits
• Works as a relay bypass or upgrade to factory wiring
• Durable for on‑road and off‑road environments

Who is this for: FASTSTORM's Electric Fuel Pump Relay Kit is aimed at mechanics, DIY enthusiasts, and performance builders who need a dependable way to deliver full battery voltage to a fuel pump or other 12V device. It’s ideal for anyone replacing a failing relay, upgrading an aging harness, or stabilizing fuel pressure by eliminating voltage loss in thin factory wiring. If you want a robust, weather‑resistant relay solution with clear labeling and a complete parts list, this kit provides a practical, install‑friendly option.
