Walbro 460 fuel pump Performance Parts & Modifications

When you start pushing serious power, the factory fuel pump (and even popular upgrades like the Walbro 255) can quickly become the limiting factor. That’s where the Walbro 460 steps in. Designed for high-horsepower builds, this pump delivers the kind of flow that modern turbocharged, supercharged, and E85-fuelled engines demand. Flowing well over 500 LPH and supporting up to 1,000 horsepower depending on your setup, it’s the perfect choice for anyone chasing big numbers without sacrificing reliability. If you’re tuned, boosted, or planning future upgrades, the 460 ensures your fuel system can actually keep up.

What makes the 460 such a standout is how efficient and stable it is under load. It’s purpose-built for forced-induction applications, where consistent fuel delivery is critical for both power and engine safety. Compared to smaller pumps, the Walbro 460 maintains stronger flow at higher pressures, which is exactly what you want when boost ramps up and injector demand spikes. It’s also fully E85 compatible, which is a must for today’s high-performance builds running ethanol blends for cooler combustion and higher knock resistance. For many of our customers, upgrading to a 460 isn’t about chasing every last horsepower - it’s about confidence and headroom.

At Empire Performance, we only supply genuine Walbro pumps and carriers, so you know you’re getting the real, high-quality hardware, not one of the many knockoffs floating around online. Whether you’re building a tough street car, prepping for drag runs, or simply future-proofing your setup, the Walbro 460 gives you the flow, reliability, and tuning stability that high-powered engines rely on. It’s one of those upgrades that immediately puts your build on solid footing, ensuring your fuel system is ready for whatever power goals come next.

Choosing the Right Walbro 460 Pump

Choosing the right fuel pump for a high-powered build isn’t just about grabbing the biggest-flowing option. It’s about matching the pump to your engine, your fuel type, and your goals. The Walbro 460 is ideal for setups that have outgrown the 255 or similar pumps and now need serious flow to stay safe under boost. With over 500 LPH on tap and support for ~1,000 HP depending on fuel and boost levels, it gives you the headroom you need for large turbo conversions, high-boost supercharger setups, and ethanol-powered builds. It’s especially popular among customers switching to E85, where fuel demand increases significantly compared to 98 pump fuel.

There are several variants of the Walbro 460 (like the F90000267, F90000274, and F90000285), which differ in relief valves, compatibility, and how they behave at higher pressures. That’s where choosing the right version matters for your specific car. Some vehicles accept the 460 into the factory pump module with minor adjustments, while others benefit from an upgraded carrier or a complete fuel pump assembly to ensure proper fitment. In many cases, we also recommend a wiring upgrade or relay kit to ensure the pump receives the voltage it needs, which is critical for consistent performance at high load.

At Empire Performance, we help customers pick the exact Walbro 460 configuration that suits their build, not just the one with the biggest number. We’ll walk you through pump variants, ethanol requirements, fuel pressure considerations, and whether a single or dual-pump setup makes sense for your horsepower goals. High-flow fuel pumps are the backbone of reliable power, and making the right choice up front means fewer issues and safer tuning down the track. We supply only genuine Walbro/TI Automotive pumps, so you can be confident that what you’re installing is built to handle the power you’re chasing.

Installation, Reliability & Ownership

Installing a Walbro 460 is generally straightforward, but because of its higher current draw and increased flow, it’s best done by someone familiar with performance fuel systems. The pump often slips into the factory fuel module with only minor adjustments, though some vehicles may require trimming, a replacement carrier, or a custom in-tank solution. A professional install also ensures the pump is properly secured, primed, and wired - all essential steps when dealing with a high-flow fuel setup. After installation, a dyno tune is almost always required. The increased flow can affect fueling behaviour, and your tuner will need to dial in the map to keep everything running safely.

From a reliability standpoint, the Walbro 460 is one of the most proven high-flow pumps on the market. It’s built to handle the demands of boosted engines, elevated fuel pressures, and the harsher characteristics of E85. Daily-driven cars running a 460 can expect excellent longevity as long as the pump is fed clean fuel and the tank stays free of debris. Noise levels are similar to other high-flow pumps, though most customers find it perfectly acceptable, especially compared to the peace of mind that comes with proper fueling under boost.

Counterfeit pumps are a huge problem online, which is why buying from a trusted supplier is critical. At Empire Performance, every Walbro 460 we sell is 100% genuine, backed by manufacturer authenticity and our own expert support. We’re here to help with fitment advice, wiring recommendations, and preparation for tuning so you get the best results from your upgrade. A properly installed and tuned Walbro 460 will support your engine reliably for years and give you the confidence to keep pushing your build without worrying about fuel delivery becoming the weak point.
