  • Help – Generator Fuel Valve Repair Suggestions?

    Posted by TowardsJoyAndFreedom on March 5, 2023 at 11:23 pm

    Hi Folks,

    Trying to repair older gasoline generator. Fuel valve leaking due to dried out gasket and can’t find replacement gasket or plug and play replacement valve. (Newer valve off Amazon for same make but newer model almost fit, but threads didn’t match – I need metric).

    I’m relatively new to working on small gas engines (have only rebuilt carbs on chainsaw and this generator). What do you recommend as easiest fix? Any considerations I need to keep in mind if I just replace with generic fuel valve and hobble together fittings to work? Looking at the gasket, does it seem realistic to try making a new one out of appropriate sized fuel line? Any advice/recommendations appreciated!

    Don’t know what it’s made from, but I have made them for motorcycle and mowers From old inner tubes and cork board. Just trace them out

      Thanks billyghoate. In this case though, the gasket is tubular not flat (or did I misunderstand you?) I should have posted a better picture of it, but you can see the gasket on the valve handle I’m holding in the upper right picture. Not super optimistic about finding the right size fuel line (both inner and outer diameter)…but thought maybe as a “hail mary”? 🤷‍♂️ Any advice on selecting generic fuel valve and sizing correct fittings? Thanks again. 🙏

      Have to agree. Trace them from gasket material and use. maybe adding a bit of red silicone to get a good seal.

        Thank you gunnsy! Here is another pic showing the gasket (or maybe I should have called it a seal?) that failed. Do you think I might have any luck making a replacement for this with fuel line or…?

        Not going to say it’s not possible. Finding the correct size will be the trick. And as far as washers to use. We use copper washers to seal airlines.

        Yeah, I agree. Thanks for your reply and telling me about copper washers. I’ll keep that in mind. Have a great day! 👍

    Ok. Now I get it. That is a conundrum! Maybe a fuel hose/washer(s) might work, but sealing correctly is an issue.

    Just looked at this site I use for parts…https://www.ereplacementparts.com/search_result.php?q=Robin+generator

    If you call them instead of searching 35 pages you might get lucky

    If you can get me the serial number and model number off the frame I can more than likely look it up. I ran a small engine shop for years.

    billyghoate – Great, Thank you! I will bookmark that resource.

    BiggKidd – Thank you so much for the kind offer. It is a Robin RGX 305D and the serial number (hard to read) I think is 101066.

    Thank you, You guys are awesome!
