Capless Gas Tank Funnel Replacement OEM#13580741,Gas Funnel for Cars Compatible with GMC Chevrolet Buick Cadillac,Portable Fuel Funnels for Automotive Use for Oil Filling

What It Is

This is a capless gas tank funnel replacement (OEM #13580741) designed for automotive fuel filler necks, not lawn mowers. It allows you to add fuel or oil to vehicles with capless fuel systems, commonly found in GMC, Chevrolet, Buick, and Cadillac models. It is not a lawn mower part—use it for cars, trucks, or SUVs with capless tanks.

Fitment & Compatibility

• Vehicle fitment: Compatible with GM vehicles (GMC, Chevrolet, Buick, Cadillac) from the early 2000s onward that use capless fuel systems. Check your owner’s manual or look for a spring-loaded flap inside the fuel filler neck—if present, this funnel fits.
• OEM vs aftermarket: This is an aftermarket replacement for GM OEM part #13580741. It should match the original in shape and function, but aftermarket tolerances may vary slightly.
• Measurements: Length is typically about 8–10 inches; the funnel tip is shaped to depress the capless flap and seal correctly. If your vehicle has a different filler neck design (e.g., threaded cap, diesel, or hybrid), this will not work.
• Not for lawn mowers: Do not use on mowers—they use standard threaded gas caps or vented tanks. This funnel is strictly automotive.

Key Things to Know

• Quality: At $6.39 and 4.8 stars (9 reviews), it’s a cheap, low-risk buy. Expect basic plastic construction—handle gently to avoid cracking.
• Installation difficulty: None. Just insert into the filler neck until it seats, then pour fuel or oil. No tools needed.
• Common gotchas: If the funnel doesn’t fully depress the capless flap, fuel may spill. Ensure it’s pushed in firmly. Also, store it in your vehicle (often in the spare tire or trunk area) so you have it when needed—many capless cars come with one from the factory, but they’re easy to lose.
• Use case: Primarily for adding fuel from a gas can or for pouring in oil (e.g., for top-offs). Not for siphoning or draining.

Should You Buy It

Buy this if you own a GM vehicle with a capless fuel system and have lost or never had the factory funnel, or if you want a cheap spare to keep in your car. Skip it if you need a lawn mower part—this is strictly automotive and won’t fit mower tanks. For $6.39, it’s a practical, low-stakes accessory for capless car owners.
