Our motorhome just turned 10 years old. We took delivery on May 17, 2005 and in all the time since, nobody else has ever touched our generator. We don’t handle every single maintenance item on the RV ourselves, but when it comes to the genset, we do it all.
Changing the Fuel Filter on an Onan Generator
The fuel filter in our Onan Quiet Diesel generator only requires replacement every 500 hours. Even though we love to boondock, the combination of solar panels and miserly power consumption allows us to use it sparingly. As a matter of fact, we put so few hours on it that we haven’t had to replace the fuel filter since prior to our debut video, nearly four years ago.
So while we’ve covered the more routine generator maintenance tasks like oil & filter change, air cleaner replacement, cleaning the spark arrestor, flushing the cooling system, and replacing the coolant, we’ve never shown the fuel filter replacement.
The time has finally arrived. Our generator’s 10th birthday present was a fresh fuel filter. For those of you who’ve asked about it, we did of course video the job.
Changing the Fuel Filter Wasn’t That Hard After All
We’ve read a number of threads on various RV forums that express some concern about this being a challenging project. This was actually one of the easiest jobs ever. Without videoing (which always seems to increase the time of every project by five-fold!) we could easily knock this job off in about 15 minutes.
Any task we can manage is preferable to having a technician do it. We get a ton of satisfaction out of doing it ourselves, not to mention the money we save. Generator maintenance, including the fuel filter replacement, is a DIY RVers dream.
Watch how we changed the fuel filter on our Onan Quiet Diesel generator.
