Onan Fuel Filter February 06, 2021, 03:38:47 pm I am attempting to change the fuel filter on the Onan generator and have come across a hose clamp that I’m not familiar with. Is this a reusable hose clamp and, if so, how do I get it off? I clamped the fuel line with vise grips but don’t want to take the hose clamp off unless I know how it works.
Re: Onan Fuel Filter Reply #1 – February 06, 2021, 03:49:33 pm It's not reusable. I remove them with snips like this:https://www.youtube.com/watch?v=NEQs_XaY9DI&ab_channel=4DIYersUnless you suspect an issue, you might not need to change the fuel filter. I'm not sure what the onan recommendation is (500 hours maybe?) , but modern gas in a fairly new vehicle is remarkably clean.Rich
Re: Onan Fuel Filter Reply #2 – February 06, 2021, 03:54:51 pm Thanks, Rich. I think the one manual I do not have is a generator manual so not sure what the recommendation is. The generator only has 104 hours on it right now so maybe I’ll just hold off until I can find out what the recommendation is. I thought I read somewhere, maybe in the Lazy Daze manual, to replace it once a year, though.Edit: I looked in the Lazy Daze manual and it makes no mention of replacing the fuel filter as part of a yearly tuneup so will hold off for now.

It's the amount of fuel that goes through it that's important, not how old it is, and hours is an easy proxy for fuel volume.

I can’t imagine that the fuel pressure going to the generator feed is very high. When it does come time to replace the fuel filter, what would be a suitable replacement clamp?Steve, the only generator info that I received when the LD was purchased was a CD with product information on it but I was unable to access the data for some reason. Good to know the manuals are online. I printed out the KY manual that Warren provided. I’ve already done most of the maintenance items except for the spark arrestor cleaning so will do that next. I bought two fuel filters, thinking it was a yearly replacement item. Anyone need one? 😉

Pick one and be sure to get the correct diameter. ;) T-BoltWorm GearNylon RatchetingCharles 1 Likes As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.
