HeuroFosh 150-175 HP V660 VRO Fuel Pump Rebuild Kit
Best for high-horsepower V6 Looper engines. This kit replaces the VRO pump on Johnson Evinrude BRP outboards with a non-oiling design, specifically fitting V6 60° Looper models rated 150–175 HP. The double-diaphragm configuration supports the higher fuel demands of these motors. The kit includes a brass/von aluminum bracket, hoses, zip ties, and mounting instructions. A minor bracket modification is required for proper fit. Not ideal for 60° engines outside the stated HP range.
QuickMarine 3CV4 VRO Fuel Pump Repair Kit
Best for older 3-cylinder Johnson Evinrude models between 60–70 HP and V4 Crossflow motors. This kit covers pre-VRO era applications and mounts on the air silencer cover where the VRO pump sat. It includes a pre-1984 pump, gasket, extra hose, bolts, zip ties, and installation instructions. Choose this if you own a pre-1984 V4 Crossflow and want a straightforward replacement without adapters. Caution: Not suitable for newer 60° Looper engines.
GAOSHUN 5007420/5007422 VRO Oil Injection Conversion Kit
Better for 90–250 HP Johnson & Evinrude outboards with V6 Crossflow or Looper configurations. This non-oil-injection pump is designed as a direct VRO replacement and includes the necessary installation hardware. It does not fit 60° applications. Best for boaters seeking broad HP compatibility within the Crossflow/Looper families. Limitation: Not compatible with 60° engines.
JLM Marine 5004558/5004559 VRO Conversion Kit
Best for Evinrude Johnson 60° V6 engines within the 150–175 HP range. JLM Marine’s kit replaces several VRO variants (including 5004558/5004559) and supports rebuilds for all VRO-equipped 60° V6 motors. It includes premix reminders. Use this option if you want a consolidated replacement for multiple VRO part families. Caution: Premixing oil is still required in the fuel as part of the installation guidance.
Johnson/OEM No VRO PreMix Conversion Kit 5007422
Best for older Johnson/Evinrude/OMC setups that require a straightforward No-VRO pre-mix conversion. The kit replaces the prior part number 438402 and is sold individually. It is suitable for users who want a direct-fit replacement without additional adapters. Caution: Always verify compatibility with your specific model year and configuration.
Buying Guide
Key considerations when choosing a VRO fuel pump conversion kit include engine compatibility, bracket and bracket modification needs, and whether the kit supports premixed fuel operation. Consider the following:
- Engine configuration: Looper versus Crossflow, and 60° versus 90° layouts affect bracket fit and mounting.
- Horsepower range: Kits specify HP compatibility; selecting the wrong range can lead to installation challenges or suboptimal operation.
- Bracket modification: Some kits require removing a portion of the bracket; assess whether you’re comfortable with minor metalwork or if professional installation is preferred.
- Oil premix requirement: Some no-oil designs require premix in the fuel supply; ensure you understand mixing ratios and oil type to avoid engine damage.
- Included hardware: Look for kits that provide hoses, gaskets, bolts, and install instructions to simplify installation.
Common installation considerations
- Verify that your model year and engine family match the kit’s stated compatibility.
- Prepare for bracket modification if required, and ensure you have basic tools for mounting.
- Follow installation instructions exactly to avoid fuel leaks or improper mixture ratios.
FAQ
- What is a VRO fuel pump conversion kit? A replacement kit that allows non-oiling fuel delivery for Johnson Evinrude/BRP outboards by substituting the original VRO pump with a premix-compatible design.
