1/4" 90 Degree Fuel Shut Off Valve Fuel Filter Fuel Line Hose Kit for Tecumseh 35857 B&S 697944 698181 494539 Riding Lawn Mower

What It Is

This is a complete fuel line replacement kit that includes a 1/4-inch 90-degree shut-off valve, fuel filter, and hose, designed for small engines on riding lawn mowers and tractors. It’s intended to replace worn or clogged fuel system components, letting you shut off fuel for storage or repairs without draining the tank.

Fitment & Compatibility

• Check hose inner diameter: Must be 1/4" (6.35mm) – measure your existing fuel line with a caliper or drill bit.
• OEM cross-reference: Fits Tecumseh 35857, Briggs & Stratton 697944, 698181, 494539. Not universal—verify your engine model number (e.g., 10.5 hp Tecumseh or B&S single-cylinder).
• Valve orientation: 90-degree shut-off is meant for tight spaces near the carburetor. Confirm your mower has clearance for the valve handle to rotate fully.
• Deck size irrelevant: This kit fits the engine fuel system, not the deck. Ignore cutting width—focus on engine make and model.

Key Things to Know

• Installation difficulty: Easy (10-15 minutes). No special tools—just pliers and a razor blade to cut hose to length. No thread sealant needed on the valve barbs.
• Quality: Valve is brass with a plastic handle. Filter is clear plastic with a paper element. Works fine for seasonal use; not heavy-duty for commercial mowing.
• Common gotcha: The hose may be slightly long for some mowers—cut it carefully to avoid kinks. The filter arrow must point toward the carburetor (fuel flow direction).
• Shut-off tip: Use the valve to pinch off fuel for carburetor bowl removal or winter storage—prevents leaks and fuel evaporation.

Should You Buy It

Yes, if you have a Tecumseh or Briggs & Stratton riding mower with 1/4" fuel line and need a low-cost, complete replacement kit. It’s a solid value for DIY maintenance on older or seasonal mowers, but skip it if your engine uses 5/16" or 3/16" hose—measure first.
