Fuel / Gas Cap by Yamaha

Yamaha UTV/ATV & Side by Side Gas Cap - Available at buywitchdoctors.com

Product Specifications: Genuine OEM Yamaha Fuel / Gas Cap, Part # BW4-F4610-10-00.

Keep your machine running like new with a genuine Yamaha Gas Cap paired with premium maintenance parts from buywitchdoctors.com. The gas cap seals the fuel filler opening, keeping fuel from splashing out, keeping dirt, water, and debris out of the tank, and, on many models, helping the tank vent or hold vapor pressure the way the fuel system was designed. A tight, intact cap also helps prevent fuel odors and evaporation losses, and it keeps fuel where it belongs over rough terrain. Riders most often replace a gas cap after a cracked, brittle, or warped cap, a worn or flattened seal that lets fuel or vapor leak, a cap that will not tighten or stay on, a tether that has snapped, a fuel smell around the tank, a clogged vent that causes poor fuel flow or a vacuum feel in the tank, or a lost cap from a trail ride or a tip-over.

Why Choose Genuine OEM Yamaha Parts?

Choosing original equipment manufacturer (OEM) parts ensures your vehicle maintains its factory-standard performance, reliability, and fuel efficiency. Genuine parts eliminate the guesswork of aftermarket alternatives, offering a seamless integration with your engine's configuration.

• Exact-Fit Design: Matched to Yamaha's original bolt patterns, sealing surfaces, and dimensions for a leak-resistant fit.
• Factory-Spec Quality: Built to the same standards as the parts installed on your machine at the factory.
• Peace of Mind: Skip the trial and error of universal or aftermarket parts that may not seal or align correctly.

Premium Materials & Precision Engineering

Crafted to strict factory tolerances, these components utilize high-grade alloys and chemical-resistant seals. This specialized engineering withstands harsh off-road vibrations, extreme temperatures, and modern fuel additives, preventing premature wear and leaks. The gas cap is made from fuel-resistant, UV-stable material with a precisely molded sealing gasket, accurately cut threads or locking tabs, and a built-in vent or valve where the design calls for one, so it seals tightly, resists swelling and cracking from ethanol-blended fuels, and stays secure through vibration, heat, and sun exposure.

Other Popular Parts & Secondary Accessories

• Fuel Tank Cleaner: Fuel tank cleaner helps remove varnish, rust, and debris that can build up inside the tank, especially after storage. If a missing or damaged cap let dirt or water in, cleaning the tank when you install a new cap helps protect your fuel system.
• Fuel Valve: The fuel valve controls the flow of fuel from the tank on models that use one. If you notice fuel smells or flow problems, inspect the valve and its seals along with the cap so you find the real cause.
• Fuel Tank & Components: The fuel tank and its related parts, such as the filler neck, vent fittings, and mounting hardware, work with the cap to seal and vent the system. Check the filler neck sealing surface for dents or cracks whenever you replace a cap so the new one seals properly.
• Fuel Lines & Mounts: Fuel and vent lines carry fuel and vapor to and from the tank, while mounts and clips keep them routed safely. Inspect them for cracks, kinks, and loose fittings when you service the cap, since a pinched vent line can mimic a bad cap.

Frequently Asked Questions (FAQs)

Q: How do I know when my Yamaha gas cap needs to be replaced, and how do I confirm the right one for my machine?
A: Look for cracks, warping, a worn, flattened, or missing seal, a cap that will not tighten or stay on, a broken tether, fuel smells or seepage around the filler neck, and symptoms of a clogged vent such as sputtering or fuel starvation on a full tank. Before replacing it, inspect the filler neck and its sealing surface, since dents or dirt there can cause leaks even with a new cap. Because gas caps vary by model, model year, vented versus non-vented design, and trim, confirm the correct part using your Yamaha service manual or factory schematic, or contact us with your model and VIN and we will help you match it.

Q: How do mud, water, sand, and heat affect a gas cap on the trail?
A: Mud, sand, and grit can collect around the filler neck and get into the tank if the seal is worn, and water can get past a loose or damaged cap and contaminate your fuel. Long sun exposure and heat can also dry out and crack the cap and its seal over time. Before opening the cap after a muddy or dusty ride, wipe the area clean, then check that the cap is seated and tightened correctly when you close it. Follow your Yamaha service manual for correct installation and fuel system safety guidance so your cap keeps the tank sealed.
