Midwest Can 4240 Quick Flow Spout - Fuel Can Spout Replacement Kit - Auto Shut Off Spill-Resistant Spout with Closing Valve & Cap - 2 Pack

What It Is

This is a replacement spout kit for standard 1-5 gallon portable gas cans, designed to replace broken, leaky, or missing spouts with an auto-shutoff, spill-resistant design. It’s intended for fueling lawn mowers, trimmers, chainsaws, and other small engines.

Fitment & Compatibility

Before buying, confirm your fuel can has a standard 3/4-inch or 1-inch threaded opening (most round metal or plastic cans do). This kit includes two spouts and adapters to fit both sizes. It will not fit cans with proprietary push-on or twist-lock spouts (e.g., some No-Spill, VP Racing, or old-style metal cans with riveted spouts). Measure your can’s opening diameter and thread pitch if unsure—this kit is not for metric threads (rarely found on US-market cans). Works with gas, diesel, and ethanol-blended fuels.

Key Things to Know

• Auto shutoff works by tipping the can – the spout has a spring-loaded valve that closes when the can is upright, preventing spills if knocked over. You must tilt the can to pour.
• Installation is tool-free – just unscrew your old spout, screw on the included adapter if needed, then attach the new spout. Hand-tighten only; overtightening can crack the plastic.
• Common gotcha: The spout’s flexible hose may kink if the can is stored with the spout attached. Remove the spout after fueling or store the can with the hose straight.
• Not for high-flow refueling – the auto-shutoff valve restricts flow slightly, so it’s slower than a standard open spout. Fine for topping off a mower; annoying for filling a large tank.

Should You Buy It

Buy this if you have a standard gas can with a broken or leaky spout and want a safe, spill-resistant upgrade without buying a whole new can. It’s a cheap, easy fix for occasional use. Skip it if you need a high-flow spout for fast refueling or if your can uses a non-threaded spout design.
