Installation Notes

Shut off the engine and the boat's fuel supply valve.
Place a suitable container or absorbent towels under the fuel filter to catch any spills.
Using a filter wrench, turn the old filter counter-clockwise to loosen and remove it.
Clean the filter mounting base on the engine, ensuring no old gasket material remains.
Lightly lubricate the gasket of the new filter with clean engine oil.
Screw the new filter on by hand until the gasket makes contact with the mounting surface.
Tighten the filter an additional 3/4 to one full turn by hand. Do not overtighten.
Open the fuel supply valve, prime the system if necessary, and start the engine.
Check carefully for any fuel leaks around the filter.

Troubleshooting & FAQ

How do I know if this filter fits my specific Volvo Penta engine?

This filter is designed for a broad range of Volvo Penta gasoline engines, from 4-cylinder to V8 models, including the AQ series. The best way to confirm is by cross-referencing your existing filter's part number with the numbers in our Part Number Matrix.

What is the micron rating and why does it matter?

This filter has a 10-micron rating, which is ideal for capturing small contaminants that can damage fuel injectors and carburetors while still allowing for adequate fuel flow. It balances fine filtration with high efficiency.

How often should I replace my fuel filter?

As a general guideline, marine fuel filters should be replaced every 100 hours of operation or at least once per season, whichever comes first. Refer to your engine's service manual for the specific recommended interval.

What are the signs of a clogged or failing fuel filter?

Common symptoms include engine sputtering, loss of power, difficulty starting, or stalling, especially under load. If you notice these issues, a clogged fuel filter is a likely cause and should be inspected.

Is this filter for gasoline or diesel engines?

This fuel filter is designed for use with gasoline engines only. Do not use it with diesel fuel.

Can I install this myself?

Yes, replacing a spin-on fuel filter is a common maintenance task for many boat owners. However, always follow safety precautions, work in a well-ventilated area, and ensure you are comfortable with the process. If in doubt, professional installation is recommended.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). It has been built to OEM-level specifications with comparable materials. It was manufactured in an ISO 9002 facility and is batch-inspected for consistency.
