Installation Guide

  1. Turn off the fuel supply and disconnect the engine's battery.
  2. Locate the existing fuel filter. Place a shop towel or rag underneath to catch any residual fuel.
  3. Carefully loosen the clamps and remove the fuel hoses from both ends of the old filter.
  4. Remove the old filter from its mounting bracket if applicable.
  5. Install the new filter, making sure the arrow on the filter housing points in the direction of fuel flow (towards the engine).
  6. Securely reattach the fuel hoses to the new filter and tighten the clamps.
  7. Reconnect the battery.
  8. Prime the fuel system according to your engine's manual and check thoroughly for any leaks before starting the engine.

Troubleshooting & FAQ

How can I confirm this filter fits my specific Mercury outboard?

This filter fits various 75-115HP Mercury/Mariner 4-stroke models from 2004-2011. The best way to confirm is to match your engine's serial number against the ranges listed in the 'Compatible Engine Models' table. Also, verify that your engine uses an 8mm (5/16") fuel line connection.

What direction should the filter be installed?

This is an in-line filter. It must be installed with the fuel flow arrow on the housing pointing towards the engine. Incorrect installation can block fuel flow and starve the engine of fuel.

How often should I replace my fuel filter?

As a crucial part of routine maintenance, we recommend replacing your fuel filter annually or every 100 hours of operation, whichever comes first. Please consult your owner's manual for the specific service interval recommended for your engine model.

What are the symptoms of a clogged fuel filter?

Common signs of a restricted fuel filter include engine hesitation, sputtering, loss of power, difficulty starting, or stalling, especially at high speeds. Replacing a clogged filter is a common fix to restore engine performance.
