VRO Fuel Pump Assembly – Fits Johnson/Evinrude 120-300hp V4/V6/V8

This VRO fuel pump assembly is designed for specific Johnson and Evinrude 2-stroke outboard engines, serving as a conversion to bypass the original oil mixing system. It is engineered for 120-300hp V4, V6, and V8 models, including 90° Looper and Crossflow engines from the 1990s to the early 2000s.

This unit is a direct replacement for multiple part numbers, including the current supersession 5007420. Note that installation requires using a pre-mixed fuel/oil ratio of 50:1, as the VRO (Variable Ratio Oiling) system will no longer be functional.

  • Conversion Pump: Designed to bypass the VRO oil injection system. Your engine must run on a 50:1 premix fuel.
  • Installation Profile: Features an external, bracket-mounted design consistent with OEM setups for a secure fit.
  • Complete Assembly: Includes the main fuel pump unit for a straightforward replacement.

Installation Guide

  1. Safety First: Disconnect the battery terminals and work in a well-ventilated area away from any sparks or open flames.
  2. Relieve Fuel Pressure: Follow your engine's service manual to safely relieve any pressure in the fuel lines.
  3. Disconnect Old Pump: Carefully label and disconnect the fuel lines and electrical connectors attached to the old VRO pump.
  4. Remove Old Unit: Unbolt and remove the original VRO pump from its mounting bracket.
  5. Cap Oil Inlet: This is a critical step. This replacement pump bypasses oil injection. You must securely cap the oil inlet barb on the new pump to prevent air leaks.
  6. Prepare Fuel System: From this point forward, your engine must run on a 50:1 fuel-to-oil premix in the main fuel tank.
  7. Mount New Pump: Install the new fuel pump assembly onto the bracket. Note that some V6 applications may require slight bracket modification for a perfect fit.
  8. Connect Fuel Lines: Reconnect the primary fuel inlet and the outlet line to the carburetors. The original pulse line from the crankcase should also be connected.
  9. Final Checks: Reconnect the battery. Prime the fuel system using the primer bulb until firm and thoroughly check all connections for leaks before starting the engine.

Troubleshooting & FAQ

How do I confirm this pump fits my engine?
First, cross-reference your existing pump's part number with the numbers listed in our table, including 5004558, 438400, and the current supersession 5007420. Second, check the compatible engine models table. This pump fits most 90° V4 and some V6 models, but be aware that bracket modification is sometimes necessary for V6 applications.

Does this pump work with my VRO oil injection system?
No. This is a conversion fuel pump assembly designed to eliminate the VRO system, which is a common failure point. You must permanently switch to using a 50:1 premixed fuel/oil mixture in your tank. The oil inlet on the pump must be capped during installation.

What are the signs my original VRO pump is failing?
Common symptoms include the engine failing to start, bogging down under acceleration, stalling at idle, or surging. You might also hear an inconsistent pumping sound or see visible fuel leaks from the pump body, which are signs that immediate replacement is needed to prevent engine damage.
