For Honda and Acura owners, a failing fuel pump can lead to poor acceleration, engine misfires, and unexpected breakdowns. The
16700-HL5-A01 Fuel Pump Assembly is a precision-engineered, direct replacement for the discontinued OEM part 16700-HL3-A02, designed to restore optimal fuel pressure, flow, and reliability in modern gasoline engines. This guide covers compatibility, key upgrades, installation best practices, and why choosing this OEM-grade component ensures seamless performance and compliance with emission standards.
Why the
16700-HL5-A01 Fuel Pump Matters
The fuel pump is essential for:
Consistent Fuel Pressure: Maintains 55–65 PSI for precise combustion in direct-injection engines.
High Fuel Flow: Delivers 180–220 L/hour to meet high-RPM demands.
Ethanol Resistance: Compatible with E10, E15, and E85 fuels without seal degradation.
Safety: Prevents lean conditions or sudden stalling.
Using non-OEM replacements risks:
Engine Codes: P0087 (Low Fuel Pressure), P0230 (Pump Circuit Malfunction), or P0171 (System Too Lean).
Premature Failure: Low-quality motors overheat under sustained loads.
Fuel Leaks: Inferior O-rings crack under thermal stress, creating fire hazards.
Warranty Voidance: Non-certified parts may void factory warranties.
Compatibility: Vehicles & Engines
The 16700-HL5-A01 directly replaces 16700-HL3-A02 and fits:
Honda:
Accord (2018–2024) – 1.5L Turbo, 2.0L Hybrid.
CR-V (2017–2024) – 1.5L L15BE, 2.0L Hybrid.
Civic (2016–2024) – 1.5L Turbo, 2.0L NA.
Acura:
TLX (2015–2024) – 2.4L, 3.5L V6.
RDX (2016–2024) – 2.0L Turbo, 3.5L V6.
Note: Confirm fitment via VIN or consult Honda/Acura technical bulletins.
Key Upgrades Over 16700-HL3-A02
High-Efficiency Motor: Brushless DC design with 25% longer lifespan and improved thermal management.
Dual-Filtration System: Stainless steel mesh + nylon strainer resists sediment and debris.
Advanced Seals: Fluoroelastomer (FKM) O-rings withstand -40°C to 150°C and ethanol blends.
Noise Reduction: Precision-balanced impeller minimizes vibrations and humming.
Plug-and-Play Integration: Matches OEM electrical connectors, fuel lines, and mounting brackets.
Symptoms of a Failing Fuel Pump
Engine Sputtering: Power loss during acceleration or uphill driving.
Extended Cranking: Takes 5+ seconds to start, especially when warm.
Stalling at Idle: Sudden shutdowns due to inconsistent fuel flow.
Whining Noise: Audible hum from the rear seat or fuel tank area.
Check Engine Light: Persistent P0087 or P0230 codes.
Test fuel pressure with a gauge (spec: 55–65 PSI at idle) to confirm pump health.
Installation Guide
Safety First:
Disconnect the battery and depressurize the fuel system via the Schrader valve.
Work in a well-ventilated area, avoiding sparks or open flames.
Access the Fuel Pump:
Remove rear seat cushions or trunk lining to access the fuel tank module.
Disconnect electrical connectors, fuel lines, and vent hoses.
Replace the Assembly:
Remove the lock ring securing the old pump (16700-HL3-A02) and carefully lift out the assembly.
Transfer the fuel level sensor to the new 16700-HL5-A01 pump.
Align the new assembly with the tank flange and secure the lock ring (torque: 25–35 Nm).
Post-Installation Checks:
Reconnect the battery and prime the system by cycling the ignition 3–4 times.
Inspect for leaks and test-drive to ensure smooth operation.
Why Choose 16700-HL5-A01 Over Aftermarket Pumps?
OEM Precision: Matches flow rate (200 L/hr), pressure tolerances (±2 PSI), and voltage specs.
Extended Durability: Rated for 120,000+ miles under normal driving conditions.
2-Year Warranty: Backed by certified suppliers.
Guaranteed Fitment: No modifications required.
Cheap alternatives often fail due to:
Motor Overheating: Inadequate cooling in stop-and-go traffic.
Pressure Fluctuations: Triggers ECU errors and misfires.
Seal Swelling: Degrades when exposed to ethanol blends.
