For enthusiasts seeking a dependable, high-flow fuel solution for demanding V8 applications, the Edelbrock 17301 fuel pump stands out as a robust and proven choice. Designed specifically to meet the fuel requirements of high-horsepower engines, particularly those utilizing Edelbrock's own Pro-Flo 4 electronic fuel injection (EFI) systems or other performance EFI and carbureted setups, this pump delivers the consistent pressure and volume necessary for optimal performance. If your engine build demands more fuel than a standard pump can provide, the Edelbrock 17301 offers the muscle and reliability you need.

Understanding the Edelbrock 17301 Fuel Pump

The Edelbrock 17301 is an in-tank electric fuel pump module. This means it's designed to be installed inside your vehicle's fuel tank, submerged in fuel. This design offers several key advantages:

  1. Cooling: Being submerged in fuel helps keep the pump motor cool during operation, which is critical for longevity, especially under high-demand conditions.
  2. Quieter Operation: The fuel surrounding the pump acts as a sound dampener, significantly reducing operational noise compared to many external pumps.
  3. Priming: Submerged pumps are inherently self-priming, eliminating potential start-up issues sometimes encountered with external pumps.

This pump is not a universal fit. It's engineered as a direct replacement module for specific GM vehicles, primarily trucks and SUVs from the late 1990s through the mid-2000s (commonly referred to as the GMT800 platform – think Chevrolet Silverado/GMC Sierra 1500, Tahoe, Suburban, Yukon, Avalanche, Cadillac Escalade). However, its performance characteristics make it an extremely popular upgrade choice for a much wider range of applications, especially performance builds.

Key Specifications and Performance

The Edelbrock 17301 is built for serious flow. Here are its critical specifications:

  • Flow Rate: Approximately 340 liters per hour (LPH) or about 90 US gallons per hour (GPH) at 60 PSI. This high flow rate is essential for supporting engines making significant horsepower, typically in the range of 600+ horsepower, depending on the specific engine's fuel consumption (BSFC).
  • Pressure Rating: Capable of supporting fuel systems requiring up to 75 PSI. This makes it suitable for modern high-pressure EFI systems like the Edelbrock Pro-Flo 4, as well as many other aftermarket EFI systems requiring 58-60 PSI.
  • Voltage: Operates on standard 12-volt automotive electrical systems.
  • Connections: Features standard SAE J2044 quick-connect fittings for the fuel lines. The electrical connector is a common GM-style connector.
  • Construction: Features a durable design intended for long service life under demanding conditions. It includes a built-in fuel filter sock on the inlet and often incorporates a basic pressure regulator within the module (though for high-performance EFI, an external adjustable regulator is usually recommended).

Installation Considerations for the Edelbrock 17301

Installing an in-tank fuel pump module requires careful attention. Here’s a general overview and key points:

  1. Safety First: Disconnect the negative battery terminal. Relieve fuel system pressure before disconnecting any lines (consult a service manual for the proper procedure for your vehicle). Work in a well-ventilated area, away from sparks or open flames. Have a fire extinguisher nearby.
  2. Vehicle Compatibility: Double-check that the 17301 is the correct module for your specific vehicle if you are using it as a direct replacement. If you are adapting it to another vehicle, ensure you have the correct installation kit (hanger assembly, bucket, etc.) or are prepared to modify the existing assembly appropriately. Using it outside its intended direct-fit application requires significant expertise.
  3. Access: Access is typically gained by removing the fuel tank or, in many vehicles (like trucks), through an access panel under the rear seat or in the cargo area. Removing the tank is often more time-consuming but sometimes necessary.
  4. Removing the Old Module: Once access is gained, disconnect the electrical connector and fuel lines. Carefully remove any locking rings or retaining clips holding the module in place. Gently lift the module assembly out of the tank, being mindful of the fuel level sender float arm.
  5. Preparation: Compare the new Edelbrock 17301 module to the old one. Ensure the filter sock, fuel level sender (if included or reused), and overall assembly match. Transfer any necessary components (like the fuel level sender) if the new module doesn't include them or if yours is different. Crucially, ensure the electrical connector matches. If not, you will need to splice the new connector onto your vehicle's harness, using proper soldering and heat-shrink techniques – crimp connectors are not recommended for fuel pump wiring due to vibration and the critical nature of the connection.
  6. Installation: Carefully lower the new module assembly into the tank, ensuring the filter sock isn't kinked and the float arm moves freely. Secure it with the locking ring or retainer. Reconnect the fuel lines (ensure quick-connects are fully seated and "clicked") and the electrical connector.
  7. Testing: Before fully reassembling everything, reconnect the battery. Turn the ignition key to the "ON" position (without starting the engine) for a few seconds, then off, repeating 2-3 times. This primes the system. Listen for the pump to run briefly each time. Check carefully for any fuel leaks at the connections. If no leaks are found and the pump primes, you can proceed to start the engine. Monitor fuel pressure with a gauge if possible.

Critical Installation Notes:

  • Wiring is Paramount: The Edelbrock 17301, like all high-flow pumps, demands significant electrical current. Inadequate wiring is the single most common cause of premature pump failure or performance issues.
    • Voltage Drop: Ensure the pump receives a consistent 13.5-14 volts while running under load. Measure voltage at the pump connector while the engine is running. Excessive voltage drop (more than 0.5-1.0 volt from battery voltage) indicates undersized wiring or poor connections.
    • Wire Gauge: Factory wiring for stock pumps is often insufficient for high-flow aftermarket pumps like the 17301. It is highly recommended to install a dedicated power circuit for the pump using 10-gauge or even 8-gauge wire (depending on run length and expected current draw – consult wire gauge charts), a high-quality relay, and a fuse or circuit breaker mounted close to the battery. Grounding is equally important; use a similarly sized ground wire directly to the chassis or battery negative.
    • Relay: Always use a relay triggered by the factory fuel pump circuit to handle the high current required by the pump. This protects the factory wiring and ensures full voltage reaches the pump.
  • Fuel System Compatibility: Ensure the rest of your fuel system is capable of handling the flow and pressure. This includes:
    • Fuel Lines: Stock lines, especially older rubber hoses or small diameter lines, may restrict flow or not be rated for higher pressures. Upgrade to AN-style lines or EFI-rated hose with appropriate fittings if necessary.
    • Fuel Filter: Use a high-flow fuel filter compatible with EFI pressures. Ensure it's installed correctly and replaced at recommended intervals.
    • Fuel Pressure Regulator: For EFI systems, especially high-performance ones, an external, adjustable fuel pressure regulator is strongly recommended. This allows precise pressure setting and helps maintain consistent pressure under varying flow demands. The internal regulator in the module (if present) is often insufficient for precise high-performance tuning.
  • Tank Cleanliness: When the tank is open, it's an excellent opportunity to inspect and clean it thoroughly. Any debris in the tank can clog the new pump's filter sock rapidly.

Performance Expectations and Tuning

Once correctly installed with proper supporting components (wiring, lines, regulator), the Edelbrock 17301 provides a significant upgrade in fuel delivery capability. Users can expect:

  • Stable Fuel Pressure: Under wide-open throttle (WOT) and high RPM, fuel pressure should remain steady at the set point (e.g., 58-60 PSI for many EFI systems), indicating the pump can keep up with demand.
  • Elimination of Lean Conditions: Engines that previously leaned out at high RPM or load due to insufficient fuel supply should now run safely within their target air/fuel ratios.
  • Support for Power Adders: The 17301 provides a solid foundation for engines utilizing nitrous oxide or forced induction (turbochargers, superchargers), though very high horsepower levels may eventually require dual pumps or an even larger single pump.
  • EFI Tuning: With a stable and sufficient fuel supply, tuning an EFI system becomes more straightforward and reliable. The ECU can accurately control injector pulse width without being starved for fuel pressure or volume.

Maintenance and Troubleshooting

While robust, the Edelbrock 17301, like any mechanical component, requires attention:

  • Fuel Filter: Regularly replace the main inline fuel filter according to the manufacturer's recommendations or more frequently if operating in dusty conditions or with questionable fuel quality. A clogged filter is a common cause of low fuel pressure and flow.
  • Pump Filter Sock: The sock on the pump inlet acts as a pre-filter. While not routinely replaced like the main filter, it can become clogged, especially if tank sediment is an issue. If experiencing flow problems, inspecting the sock is necessary (requires dropping the tank/module).
  • Listen for Changes: Become familiar with the sound of your pump priming when you turn the key. A change in sound (whining, screeching, struggling) can indicate impending failure or a problem like a clogged filter or voltage issue.
  • Monitor Fuel Pressure: Installing a fuel pressure gauge (mechanical or electric) is invaluable for diagnosing fuel system issues. A drop in pressure under load is a clear sign of a problem – potentially the pump, filter, regulator, or wiring.
  • Common Failure Symptoms:
    • Engine Cranks but Won't Start: No fuel delivery. Could be pump failure, wiring issue (blown fuse, bad relay, broken wire), clogged filter, or a failed pump.
    • Engine Stalls or Hesitates Under Load: Fuel starvation. Often caused by a clogged filter, failing pump, severe voltage drop, or a pinched/kinked fuel line.
    • Loss of Power at High RPM: Insufficient fuel volume or pressure. Check pressure under load.
    • Loud Whining or Humming from Tank: Can indicate a pump struggling due to restriction (clogged filter/sock), low voltage, or impending mechanical failure.

Edelbrock 17301 vs. Other Options

The fuel pump market is vast. How does the 17301 compare?

  • Stock Replacement Pumps: Vastly superior in flow rate. Stock pumps for most vehicles typically flow 120-200 LPH, insufficient for modified engines.
  • Other "High-Performance" Replacement Pumps: Many parts store "performance" pumps offer only marginally better flow than stock. The 17301's 340 LPH is significantly higher than most basic upgrades.
  • Dedicated Aftermarket Pumps (Walbro, Bosch, AEM): Pumps like the Walbro 450 LPH (commonly used as an upgrade) offer even higher flow than the 17301. However, the 17301 has the advantage of being a complete module with a hanger, often making installation simpler in its intended applications than retrofitting a "bucketless" pump. The 17301 sits in a sweet spot of flow vs. ease of installation for many popular platforms.
  • External Pumps: While external pumps can offer high flow, they are noisier, run hotter, and can be more prone to vapor lock. The in-tank design of the 17301 is generally preferred for street-driven vehicles.
