Product Details
This aftermarket replacement VRO-delete fuel pump assembly is intended for selected Johnson and Evinrude 2-stroke V4, V6 and V8 outboard applications. It is designed for installations in which the original VRO oil-injection system has been disconnected or bypassed. Engines using this pump must be operated with gasoline premixed with the correct amount of 2-stroke oil, typically at a 50:1 ratio unless the engine manufacturer specifies otherwise.
The assembly uses an external bracket-mount configuration and OEM-style fuel-line connections. It is commonly identified as a replacement or cross-reference for Johnson/Evinrude numbers including 5004558, 438400, 435555, 435556, 435558, 435560, 435782, 435784, 435953, 435955, 435936 and 5007420. Confirm the original pump, engine model and mounting arrangement before ordering.
- External bracket-mount fuel pump assembly.
- For VRO-bypassed applications using premixed fuel and oil.
- OEM-style fittings for the applicable fuel-line connections.
- Aftermarket replacement; not a genuine Johnson or Evinrude component.

Installation Notes
- Disconnect the battery and work in a well-ventilated area away from flames, sparks and other ignition sources.
- Relieve fuel-system pressure and contain any fuel before disconnecting the lines.
- Label and disconnect the fuel lines and any applicable pulse or electrical connections from the original pump.
- Remove the original pump from its mounting bracket and compare the replacement with the original before installation.
- Some V6 applications may require a different bracket arrangement or minor bracket modification. Do not modify the bracket unless the fit and clearance have been confirmed.
- Mount the replacement pump securely and route the fuel lines without kinks, chafing or sharp bends.
- Reconnect the lines and connections according to the engine service information and the labels made during removal.
- Because this is for a VRO-bypassed application, prepare and use the correct premixed fuel/oil mixture required for the engine.
- Prime the fuel system according to the engine manufacturer’s procedure, then inspect every connection for leaks before starting.
- After starting, perform another leak check and confirm stable operation before returning the boat to service.
Troubleshooting & FAQ
Will this pump work with an active VRO oil-injection system?
No. This is a VRO-delete style fuel pump assembly for an application where the oil-injection system has been disconnected or bypassed. Use the engine manufacturer’s specified premixed gasoline and oil mixture.
How can I identify a failing fuel pump?
Possible symptoms include difficult starting, bogging, stalling, sputtering at higher speed, loss of power and uneven running. Check fuel lines, filters, pulse connections and other fuel-system components before replacing the pump.
Does this fit every V4, V6 or V8 model listed?
No. The engine groups and horsepower ranges are general application guidance, not a guarantee for every model. Confirm the exact model, year, serial range, original part number and mounting arrangement. Some V6 installations may require bracket changes or may not be suitable.
Is this a genuine OEM component?
No. This is an aftermarket replacement part intended to correspond to the listed reference numbers. It is not manufactured or branded as a genuine Johnson or Evinrude component.
How often should the fuel pump be replaced?
There is no universal replacement interval. Replace the pump when testing or operating symptoms indicate failure, or when it shows leakage, deterioration or other damage. Fuel quality, ethanol exposure and storage conditions can affect service life.
How fast is shipping and what does it cost?
Typical worldwide transit is 5–15 days. Standard shipping is free; expedited options appear at checkout where available.
What is the warranty and return policy?
This part is covered by a 1-year warranty against manufacturing defects under normal use. Returns are accepted within the standard return window for unused items in their original condition. Contact support with your order details for warranty or return instructions.
