Fuel contamination — sediment, water, and debris from ethanol-blended fuel or aging tanks — is one of the most common causes of injector wear, fuel pump damage, and rough running on Volvo Penta inboard engines. The Volvo Penta #21746575 is the correct OEM fuel filter for your application, engineered to the exact micron rating, bypass pressure, and thread specification your engine's fuel system requires. Use it at every service interval to keep clean fuel flowing and protect the components downstream.

Additional Information

Why Fuel Filter Maintenance Matters on Volvo Penta Inboards:

Marine fuel systems face contamination challenges that automotive engines rarely encounter — ethanol-blended fuel that absorbs water, tanks that sit over winter and accumulate sediment, and fuel that degrades between seasons. A clogged or bypassed fuel filter allows that contamination to reach your fuel pump and injectors, leading to:

• Hard starting or no-start conditions
• Rough idle and engine stumble under load
• Fuel injector clogging and premature wear
• Reduced fuel economy and power output
• Fuel pump damage from restricted or contaminated flow

Replacing your Volvo Penta fuel filter at every service interval is one of the most cost-effective maintenance steps you can take to protect your inboard engine investment.

Why Choose the OEM Volvo Penta Filter:

• Correct micron rating — engineered to filter at the specification your Volvo Penta fuel system requires
• OEM bypass valve pressure — opens at the correct pressure to protect fuel flow without allowing unfiltered fuel to bypass prematurely
• Exact thread and seal spec — direct fit with no adapter or modification required
• Genuine Volvo Penta quality — built to the same standard as the filter that came with your engine

Frequently Asked Questions

1. How do I confirm this is the right fuel filter for my engine?
Cross-reference part #21746575 against your Volvo Penta engine's parts diagram or service manual. If you have your engine model and serial number, contact us at MacombMarineParts.com and we'll confirm the correct part before you order.

2. How often should I replace my Volvo Penta fuel filter?
Volvo Penta generally recommends fuel filter replacement at each annual service interval or every 100–200 hours of operation, whichever comes first. Replace sooner if you notice symptoms of fuel restriction — hard starting, rough running, or reduced power — or any time you suspect fuel contamination from water or sediment.

3. Can I use an aftermarket fuel filter instead of OEM?
We recommend using the OEM Volvo Penta filter for this application. Marine fuel systems operate under specific pressure and flow requirements, and OEM filters are engineered to the correct micron rating, bypass valve pressure, and thread spec for your engine. An incorrect aftermarket filter can restrict fuel flow, bypass prematurely, or fail to seal properly — all of which can cause engine damage that far exceeds the cost of the correct part.

4. What are signs that my fuel filter needs replacing?
Common indicators include hard starting, rough idle, hesitation or stumbling under load, reduced top-end power, and increased fuel consumption. If your engine has been running on old or potentially contaminated fuel, replace the filter as part of your next service even if symptoms aren't yet present.
