VRO Fuel Pump Rebuild Kit – Fits Johnson/Evinrude 3-Cylinder 60-70 HP & V4 Crossflow Outboards (Pre-1984)
This fuel pump rebuild kit is a replacement for Johnson/Evinrude outboard motors, specifically pre-1984 3-cylinder models rated at 60-70 HP and V4 Crossflow models originally equipped with a VRO (Variable Ratio Oil) pump.
This unit replaces the original VRO pump. Crucially, it does not perform oil mixing; the engine must be run on a pre-mixed fuel and oil solution at a 50:1 ratio to ensure proper lubrication and prevent engine damage.
-
Direct Replacement: Designed to replace the pre-1984 VRO fuel pump system on specific Johnson/Evinrude models.
-
Fuel Requirement: Requires pre-mixed gasoline and 2-stroke oil at a 50:1 ratio.
-
Installation: Includes a bracket for mounting on the silencer cover.

Installation Guide
-
Safety First: Disconnect the battery terminals and ensure the engine compartment is well-ventilated.
-
Relieve Fuel Pressure: Carefully relieve any pressure from the fuel system.
-
Disconnect Old Pump: Disconnect the fuel lines from the existing VRO pump. Have rags ready to catch any residual fuel.
-
Remove Old Unit: Unbolt and remove the old VRO pump and its bracket from the silencer cover.
-
Mount New Pump: Install the new fuel pump and aluminum bracket assembly onto the engine.
-
Connect Hoses: Attach the inlet and outlet fuel hoses to the new pump, ensuring all connections are secure to prevent leaks.
-
Critical Pre-Mix Fuel: This is a non-oiling pump. Your fuel tank must contain a 50:1 gasoline-to-oil mixture before proceeding.
-
Prime and Test: Prime the fuel system using the primer bulb until firm. Start the engine and carefully inspect for any fuel leaks around the pump and hoses.
Troubleshooting & FAQ
Q: How do I confirm this fits my engine?
A: This kit is made specifically for pre-1984 Johnson/Evinrude 3-Cylinder (60-70 HP) and V4 Crossflow outboards that used the VRO pump system. Please review the compatible models table carefully. The key is that this replaces an existing VRO pump on older models.
Q: My old pump was a VRO pump. Do I still need to mix oil in my gas with this kit?
A: Yes, absolutely. This kit is a non-oiling replacement that eliminates the VRO system's oil-mixing function. You must use pre-mixed fuel and oil at a 50:1 ratio (e.g., 1 pint of oil to 6 gallons of gasoline) to prevent catastrophic engine damage.
Q: What are the signs of a failing fuel pump?
A: Common symptoms include the engine sputtering or bogging down at high speeds, loss of power, difficulty starting, engine stalling, or excessive fuel consumption.
Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
