Read articles →This is part 4 of a multi-part 50-hour service series on a Kubota BX23S, focused specifically on replacing both fuel filters (one top-mounted, one tucked under a skid plate). It's a real-time, unpolished hands-on walkthrough showing the actual struggle of stubborn hose clamps, diesel spills, and awkward access points, rather than a clean tutorial. Best for owners who want an honest, warts-and-all look at this specific job before attempting it themselves.
An owner-operator filming their own DIY maintenance with a helper holding the camera, presented candidly rather than polished for production.
There are two fuel filters, one mounted on top of the machine and one tucked underneath behind a skid plate.
A little spray lubricant applied to the hose helped it slide off the crimped filter end when it would not come off easily by hand.
Yes, it sits behind a skid plate with the hose clamp positioned awkwardly, making it more difficult to access than the top filter.
The old filter appeared brown and visibly dirty with some diesel still in it, compared to the clean white new filter.
