K&N Performance Electric Fuel Pump 1-2 PSI

Designed with cutting-edge technology and premium materials, this fuel pump is the top choice for enthusiasts and professionals seeking superior performance for a wide range of applications. Whether you’re upgrading a classic car, powering a generator, or enhancing a motorcycle, the K&N 81-0400 sets the industry standard for low-pressure fuel delivery, making it the best investment for your fuel system needs.

Why K&N Over All Others?

Performance: Delivers a consistent 15 gallons per hour (GPH) at 1-2 PSI, perfectly suited for carbureted engines, ensuring optimal fuel flow without overwhelming your system. Its self-regulating 12-volt design eliminates vapor lock and flooding, providing seamless operation under demanding conditions.

Quality: Crafted in the USA by K&N Engineering, a global leader in performance parts since 1969, this pump features corrosion-resistant housing and a robust design with no bearings or diaphragms to wear out, guaranteeing exceptional durability over cheaper alternatives.

Whisper-Quiet Operation: Unlike noisy, low-quality pumps, the 81-0400 operates silently, enhancing your driving experience while maintaining top-tier performance.

Versatile Compatibility: Compatible with a wide array of fuels, including gasoline, diesel, biodiesel, E85, methanol, ethanol, and alcohol, making it the go-to choice for diverse applications, from vintage cars to marine and powersports vehicles.

Outperforms the Competition: Customer reviews highlight its reliability over inferior Chinese-made pumps, with users reporting instant priming, dependable daily use, and flawless integration with systems like Stromberg 97 carburetors and Weber 32/36 carbs. Unlike others, the K&N pump avoids common failures, such as excessive noise or premature breakdowns.

What’s Included?

The K&N 81-0400 Performance Electric Fuel Pump comes complete with everything needed for a hassle-free installation:

  • K&N Inline Fuel Pump: Self-priming, 12-volt electric pump, engineered for 15 GPH at 1-2 PSI.
  • High-Quality Fuel Filter: Ensures clean fuel delivery, protecting your engine from contaminants.
  • Complete Installation Hardware Kit: Includes hose barbs (0.31-inch inlet/outlet), mounting brackets, two bolts, two color-coded wires, and necessary fittings for quick and secure setup.
  • Installation Instruction Sheet: Detailed, step-by-step guide for easy installation, even for DIY enthusiasts.
  • K&N 10-Year/Million Mile Limited Warranty: Covers defects in materials and workmanship, offering peace of mind unmatched by competitors.

Vehicle Fitment Data

The K&N 81-0400 features a universal design, making it compatible with a vast range of vehicles and applications requiring a low-pressure fuel pump (1-2 PSI). Below is a non-exhaustive list of common fitments based on verified applications and customer feedback:

  • Classic and Vintage Cars:
    • Ford Model A (1927-1931) with Stromberg 97 carburetors.
    • Ford F-100 Pickup (1968-1972) with Rochester or Holley carburetors.
    • Chevrolet 261-powered vehicles (1950s-1960s).
    • Triumph Spitfire (1972) with original carburetors.
  • Motorcycles:
    • Honda VT1100C Shadow Cruiser (1988) requiring 2-3 PSI.
  • Powersports and Utility Vehicles:
    • Kawasaki Mule (various years) for farm and utility use.
  • Marine and Generators:
    • Honda EU3000is Generator for extended fuel tank applications (25-gallon tanks).
  • Other Applications:
    • Compatible with carbureted vehicles, boats, and small engines using diesel, biodiesel, gasoline, E85, methanol, ethanol, or alcohol-based fuels.

Note: This pump is ideal for carbureted systems requiring 1-2 PSI. For higher-pressure needs, consider K&N’s 81-0401 (1.5-4 PSI), 81-0402 (4-7 PSI), or 81-0403 (7-10 PSI) models. Not legal for sale or use in California on pollution-controlled vehicles.

Performance Comparison

  • Vs. Generic Chinese Pumps: Users report frequent failures, excessive noise (“like a coffee can full of bolts”), and inconsistent pressure with low-cost alternatives. The K&N pump primes instantly, runs quietly, and maintains steady 1-2 PSI, even under daily use.
  • Vs. Other Premium Brands: Unlike Carter or Walbro pumps, which may require additional regulators or complex setups, the K&N 81-0400’s self-regulating design simplifies installation and ensures compatibility with a broader fuel range.
