Product Description

The K&N 81-0400 Inline Electric Fuel Pump is engineered as a universal upgrade or replacement for low-pressure fuel systems. With a flow rate of approximately 15 gallons per hour at only 1-2 psi drop, it is ideal for applications such as carbureted or low-pressure EFI setups, helping to prevent vapor lock, flooding and general fuel delivery issues. Compatible with gasoline, diesel, E85, methanol and other fuel blends, this pump offers flexibility across many vehicle types.

Installation is straightforward; the inline compact design allows you to mount it in almost any orientation (consult installation instructions for orientation recommendations). Because it is a universal fit product rather than vehicle-specific, you'll need to verify your hose size, fuel pressure requirement and electrical compatibility. The included filter and hardware simplify setup and help you get running quickly.

Please verify your system requirements (hose size, feed/return configuration, pressure, compatibility with fuel type) before install. While universal in nature, this product is not vehicle-specific and should be installed with appropriate safety devices such as fuses and check-valves. This product is **not CARB-legal for sale or use in California on pollution-controlled vehicles** unless explicitly stated otherwise. Ideal for enthusiasts and custom-builds seeking improved fuel-system reliability and flow under low-pressure conditions.
