I have yet to see such a complete, simple and informative example of working on a fuel sstem, as you have presented here. If you're not an instructor at a community college or similar place,,,, YOU SHOULD BE. Very nice job of this presentation and narration. . Thank You.
Thanks for showing ALL of the steps unlike many of the other videos on youtube. I haven't changed a filter in a while and needed a good refresher. Opening up the fuel petcocks to refill the filters sounds a little risky to me though, maybe OK dockside but you don't want to take the risk of having to bleed an engine if you need to switch out filters in an emergency situation. Thanks again from NYC.
Thanks. That's very useful, as I'm about to change my fuel filter for a RACOR after experiencing problems with the type currently fitted. Greetings from Wales, UK.
Great, clear video, thank you. I have 3 to change before going out to a lumpy sea for the first time since acquiring the boat, so this was very helpful and will give me confidence to do it myself
OK gentlemen. This will settle this question about the terms "primary" and "secondary" fuel filters once and for all. I have in front of me three books on diesel engines: Paul Dempsey's Troubleshooting and Repairing Diesel Engines; Nigel Calder's Marine Diesel Engines; and Thomas Reale and Michael Johnson's Your Boat Belowdecks. All three refer, starting at the fuel tank, to the first fuel filter (usually mounted remotely from the engine), as the "primary" filter, and the next filter (usually mounted on the engine) as the "secondary" filter. All three mention that the primary filter is a coarser filter that filters out the big stuff, and that the secondary filter is a finer filter which filters out the smaller stuff. It's irrelevant what terms the engine manufacturers use; they don't know how the engine will be installed in various applications. When they sell an engine to a manufacturer it typically only has the secondary filter, which is mounted on the engine. The primary filter is usually added by the boat manufacturer who installs the engine in a given boat.
People always reverse the designation of the fuel filters because of their position in the fuel supply line. Properly, the PRIMARY filter is the one attached to engine and is the LAST in line before the injector pump. The SECONDARY is the Racor mounted somewhere off of the engine that filters fuel and separates water BEFORE the lift pump.
Multiple sources disagree with your statement. “Primary” refers to the coarser filter, in my case the Racor (10 micron), the first filter that the fuel passes through. “Secondary” refers to the finer of the two filters, in my case the engine-mounted filter, which is the second filter that the fuel passes through. It is a 3-4 micron filter.
@@davidvonwolffersdorff2385 Yes - that's what I said. People have reversed the proper terminology because they think that "primary" means "first" in the supply line. The essential "primary" filter is a component of the engine. The Racor is an add-on "secondary" filter.

Thank you for your thoughtful comments!
Outstanding video! Perfectly explained as I needed a refresher. Thanks for making this video!

Most welcome!

Thanks. We love the UK. We haven’t been to Wales yet. We are big fans of Vera which we stream on Britbox. Good luck with your Racor.

Glad to hear that. Good luck!
Thank you for taking the time to make these videos. Saves me a bunch of money
It’s easy. Good luck!

I see we both graduated from your Thistle i crewed on with you, great to bump into you - Frank
Frank, good to hear from you. How can I contact you privately to catch up on things?
Thank you, I appreciate you taking the time to explain this. New to me and very helpful.
Most welcome!
Useful, need to swap mine for the first time . thanks
Great video, explained very well!
Glad you found it helpful!
Good job David ! Most videos aren't really clear .
Thanks!
Thanks very much. Extremely helpful for a noob like me.
Glad you liked it!
Thanks for the Video now ill do mine
Also note if you want to use the filter also as a water separator you want to use the 30 micron filter. Racor says the finer filters wont do it.
Thanks for the video.
You’re welcome!
what is the name of this product and can i get it on amazon
Parker/Racor 2010 10 micron fuel filter. Yes, it is available at Amazon.
what racor is that?
It’s a Racor 500.
thank you~ @@davidvonwolffersdorff2385
Also you need to clean fuel bowl and water separator !!!!
You’re right:) Thank you!

@@bobbeckstead8340 .....No...... it isn't what you said......it's the exact opposite ....and David is correct.
@@bricktopperheadon5490 Nope.
