Here's a 5-foot length of black fuel line hose with a 1-inch inner diameter (that's about 25mm ID, 36mm OD). Perfect for replacing cracked, brittle, or leaking fuel lines on small engines like lawn mowers, ATVs, generators, go-karts, or motorcycles. Made from oil-resistant material to handle gasoline and diesel without breaking down. Brand new, comes coiled up in simple packaging – might just be a poly bag with a label. From uxcell, a decent supplier for generic parts. Super flexible and easy to cut to the exact length you need with a sharp knife or hose cutter. Just make sure your clamps fit this diameter. A must-have for spring tune-ups when you discover last season's fuel line has dry-rotted. Much cheaper than buying OEM hose by the foot at an auto parts store. Also works for low-pressure oil lines or other fluid transfer. California Prop 65 warning applies (typical for rubber/petroleum products). Keep your engine running smoothly and safely – no one wants fuel leaks near a hot engine. Great for DIY mechanics and small engine repair shops. Stock up for multiple projects. Get your equipment fueled up and ready for work or play.
