VRO Fuel Pump Repair Kit – Fits Johnson/Evinrude V4 60° Looper Models 90-115 HP (Replaces 5007420)
This VRO fuel pump conversion kit is designed for Johnson/Evinrude 90-115 HP, V4 60° looper engines (1995–2006). It is a direct-fit replacement for carbureted models originally equipped with a VRO oil injection system, converting the engine to run on a premixed fuel/oil blend.
This kit replaces the original VRO system with a standard fuel pump, which requires using a 50:1 premix ratio (1 pint of oil to 6 gallons of gasoline). It serves as a direct replacement for Johnson/Evinrude part numbers 5007420, 5007422, 174955, 435555, 436203, 438400, 5004558, and 8402-460.
-
Conversion System: Replaces the VRO oil injection system, simplifying the fuel system and requiring a 50:1 fuel/oil premix.
-
Direct Installation: Mounts directly to the existing vapor tank or bracket with included hardware for a straightforward bolt-on process.
-
Complete Kit: Includes the fuel pump, mounting bracket, hoses, bolts, and zip ties for a comprehensive installation.

Installation Guide
-
Safety First: Disconnect the battery and work in a well-ventilated area away from any open flames or sparks.
-
Locate the VRO Pump: Identify the existing VRO pump and fuel lines on your engine. Place a rag underneath to catch any fuel drips.
-
Disconnect Lines: Carefully disconnect the fuel inlet, fuel outlet, oil inlet, and pulse limiter hoses from the VRO pump. Disconnect the warning horn and oil tank electrical connectors.
-
Remove Old Pump: Unbolt and remove the VRO pump assembly. Thoroughly clean the mounting surface.
-
Install New Pump: Mount the new fuel pump assembly using the provided bolts. Ensure it is securely fastened.
-
Connect Fuel Lines: Attach the main fuel inlet and the outlet line to the carburetor. Plug the pulse fitting on the crankcase.
-
Disable Oil System: Since the oil pump is disconnected, you must permanently switch to premixed fuel. Disconnect and remove the oil tank.
-
Premix Fuel: Mix your fuel and oil at a 50:1 ratio (1 pint of 2-stroke oil to 6 gallons of gasoline) before filling the tank.
-
Final Checks: Reconnect the battery. Prime the fuel system using the primer bulb until firm. Check all connections for leaks before starting the engine.
Troubleshooting & FAQ
How do I confirm this fits my engine?
This pump is specifically for Johnson/Evinrude V4 60° Looper engines (90-115 HP) from 1995-2006. Please verify your exact model and year against the compatibility table above. It is intended for carbureted models only, not fuel-injected (FICHT) systems.
Does this pump use the VRO oil injection system?
No, this is a conversion kit that completely replaces and eliminates the VRO system. After installation, you MUST use a 50:1 fuel-to-oil premix in your fuel tank for proper engine lubrication.
What are the signs my original VRO pump is failing?
Common symptoms include the engine running rough, surging, or stalling; visible fuel or oil leaks around the pump body; or the warning horn sounding for no apparent reason. A faulty VRO can lead to incorrect oiling and catastrophic engine damage, making replacement critical.
