Be sure to confirm only one fuel filter... I did my research on my Onan 7500, finding that it actually uses two fuel filters. That said they were easy to replace and I'm glad I did it myself. I simply used a pair of channel locks to pinch off the fuel supply.
You didn't really say what the reason for the filter replacement was... Just maintenance, or a problem? I was having a problem with the genny running for 10-15 minutes and quitting. After replacing the fuel filters and running a bunch of Seafoam through it, I learned of a problem with the fuel pumps used at the time of production. I replaced the fuel pump for about $25 bucks from Amazon, and it now runs like new.
