Product Details
This VRO fuel pump conversion kit is an aftermarket fuel-only pump solution for selected Johnson and Evinrude 150–175 HP two-stroke outboards that have had the oil-injection function of the VRO system bypassed. It is intended for installations using gasoline and oil premixed at the ratio specified for the engine by the engine manufacturer or service manual.
The fuel pump kit is listed as a replacement for Johnson/Evinrude part numbers 5007420 and 5007422. Catalog records associate these numbers with multiple Johnson and Evinrude 150–175 HP two-stroke applications, including model years from the mid-1990s through 2001. Because fitment varies by exact model and serial-number range, confirm your complete engine model and the original pump configuration before ordering.
- Fuel-only replacement for converted or bypassed VRO systems.
- Double-diaphragm pump design for suitable multi-cylinder outboard applications.
- Includes an aluminum mounting bracket and installation hardware listed below.
- Hose-barb connections support standard fuel-line installation.

Engine & Model Compatibility
Use the application information below as a starting point, not as a substitute for checking the complete model and serial number. The catalog evidence reviewed confirms 5007420 and 5007422 in multiple Johnson and Evinrude 150–175 HP two-stroke applications, but does not establish universal fitment across every V6, 60-degree, Looper, or VRO configuration.
| Brand | Application range | Rated HP | Stroke | Documented model years | Replacement reference | Fitment note |
|---|---|---|---|---|---|---|
| Johnson/Evinrude | Selected outboard models | 150 | 2-Stroke | 1994–2001 in reviewed catalog records | 5007420 or 5007422 | Confirm exact model, serial range, pump layout, and bracket position. |

Installation Notes
- Disconnect the battery, work in a well-ventilated area, and relieve fuel-system pressure before beginning.
- Identify and label the fuel lines and any electrical connections associated with the original VRO assembly.
- Remove the original pump and inspect the fuel lines, fittings, and mounting area for damage or contamination.
- Important: A minor filing or trimming operation on the aluminum bracket may be required for clearance on some applications. Do not modify the pump body or fuel connections.
- Mount the replacement fuel pump securely and route the hoses away from heat, sharp edges, and moving components.
- Reconnect each fuel line to the correct barb and secure every connection to prevent leaks.
- Confirm that the oil-injection system has been properly bypassed or otherwise serviced according to the engine service procedure before operating the engine.
- Prime the fuel system according to the engine service manual, inspect carefully for leaks, and verify proper fuel delivery before starting.
Troubleshooting & FAQ
Is this a direct fit for every Johnson/Evinrude 150–175 HP two-stroke outboard?
No. The replacement references are used across multiple applications, but mounting position, bracket clearance, hose routing, model, and serial conditions can vary. Compare the original pump and verify the complete engine model before installation.
Do I need to premix fuel with this pump?
This is a fuel-only conversion pump. It does not provide variable-ratio oil injection. It should be used only on an engine whose oil-injection arrangement has been intentionally bypassed or converted, with the gasoline-to-oil premix ratio specified for that engine.
Can this pump replace an OEM VRO pump without changing the fuel system?
No. The original VRO assembly may combine fuel pumping with oil metering, while this kit is intended for fuel-only operation. The oil-injection system must be addressed correctly, and all fuel and oil-related connections must be identified before use.
What symptoms can indicate a failing fuel pump?
Possible symptoms include hard starting, loss of power, bogging, surging, stalling, or inconsistent performance under load. Inspect the tank, primer bulb, fuel lines, filters, and pump before replacing parts, and follow the engine service manual for testing.
Will the bracket always install without modification?
Not necessarily. The included aluminum bracket is designed for the listed applications, but minor filing or trimming may be required for clearance on some engines. Verify the fit before permanently tightening the assembly.
Is this an OEM component?
No. This listing is for an aftermarket replacement and conversion kit. Johnson and Evinrude names and part numbers are used only to identify applicable replacement references.
Shipping speed and cost?
Typical transit is 5–15 days where available. Shipping options and delivery estimates are shown at checkout and may vary by destination.
Warranty and returns?
Warranty and return eligibility are governed by the current store policy. Contact support with your order details before returning or disassembling a suspected defective part.
Safety & Important Info
- Verify the complete engine model, serial information, original pump arrangement, hose routing, and bracket configuration before purchase.
- Do not use this fuel-only pump as proof that an engine's oil-injection system is functioning.
- Use only the fuel and oil mixture specified for the converted engine.
- Inspect every fuel connection for leaks before starting and after the first test run.
- Professional installation is recommended because incorrect fuel-system or oil-injection work can cause fire, engine damage, or personal injury.
