Product Details

This VRO conversion fuel pump is intended for Johnson, Evinrude, and OMC outboards with a failed or problematic VRO system. The company application covers large 200, 225, 250, and 300 HP V6 or V8 engines, as well as 120, 130, and 140 HP Looper V4 models.

As a conversion pump, it is used when the original VRO arrangement is being removed or bypassed. The pump is supplied as a single fuel pump, not as a repair kit or complete VRO assembly. Verify the original pump, engine configuration, and connection layout before ordering.

• Conversion fuel pump for listed Johnson, Evinrude, and OMC outboard applications
• Designed for 120–140 HP Looper V4 models and 200–300 HP V6 or V8 models with VRO problems
• Uses the existing mounting arrangement; bracket or hardware changes may be required during installation
• For a VRO conversion, follow the engine manufacturer's required oiling procedure and use the correct premix ratio after oil injection is disabled

Installation Notes

1. Disconnect the battery and relieve fuel-system pressure before beginning work.
2. Identify the exact engine model and compare the original pump, ports, hoses, and mounting points with the replacement.
3. Remove or bypass the existing VRO components according to the engine manufacturer's service procedure.
4. Reuse the existing mounting arrangement only if it securely fits the replacement pump. Bracket or hardware modification may be required.
5. Connect the fuel lines to the correct inlet and outlet ports and secure every connection against leaks.
6. When the oil-injection function is disabled, establish the correct premix procedure for the engine before operation. Do not run the engine without adequate lubrication.
7. Prime the fuel system, inspect all connections for leaks, and test-run the engine in a controlled environment before normal use.

Troubleshooting & FAQ

Is this a complete VRO pump assembly?

No. This listing is for one VRO conversion fuel pump. It is not confirmed to include a mounting bracket, complete VRO assembly, hoses, fittings, or a repair-kit set.

What engines is this pump intended for?

The listed applications are 120, 130, and 140 HP Looper V4 models, plus 200, 225, 250, and 300 HP V6 or V8 Johnson, Evinrude, and OMC outboards with a failed or problematic VRO system.

Do I need to change the oiling procedure after a VRO conversion?

Yes. A conversion that disables oil injection requires a properly prepared lubrication plan, normally including the correct fuel premix specified for your engine. Follow the engine manufacturer's service instructions and do not rely on an inoperative oil-injection system.

Can I install it without modifying the existing bracket?

Not necessarily. The existing mounting arrangement may be reusable, but bracket or hardware modification can be required to secure the replacement pump. Compare the pump and mounting points before installation.

Does this fit every Johnson or Evinrude engine from 120 to 300 HP?

No. The horsepower range alone does not confirm compatibility. The listed application is limited to 120–140 HP Looper V4 models and 200–300 HP V6 or V8 models with the relevant VRO conversion requirement. Confirm the exact model, year, serial number, and original part before ordering.

Is this an OEM component?

This is an aftermarket replacement. The manufacturer reference numbers are provided for application identification and comparison only; this product is not represented as an OEM-branded component.

What should I check before ordering?

Compare the original pump, manufacturer reference number, port arrangement, mounting points, engine family, horsepower, and VRO configuration. If any of these details differ, consult a qualified marine technician before purchase.
