1723165SM Oil Drain Hose Compatible with briggs and stratton oil drain hose Model Series 29, 30, 35 & 38 40, 44 & 49 Engines

What It Is

This is an aftermarket oil drain hose designed to replace the original equipment on Briggs & Stratton engines in the Model Series 29, 30, 35, 38, 40, 44, and 49. It simplifies oil changes by routing the drain to a more accessible spot, eliminating the need to tip the mower or crawl underneath.

Fitment & Compatibility

• Engine Models: Confirmed for Briggs & Stratton Model Series 29, 30, 35, 38, 40, 44, and 49. Check your engine’s model number on the valve cover or blower housing.
• OEM Replacement: This is an aftermarket part (part number 1723165SM), not an official Briggs & Stratton OEM part. It may vary slightly in hose length or fitting angle.
• Measurements: The hose typically has a 3/8″ ID and a brass barbed fitting. Measure your existing drain port thread (usually 1/4″ NPT) and hose length (approx. 12–18″) to confirm fit.
• Mower Type: Works on walk-behind mowers, tractors, and zero-turns using these engine series. Not for engines with a different drain plug configuration.

Key Things to Know

• Installation Difficulty: Easy—just unscrew the existing drain plug, screw in the hose fitting, and route the hose. No special tools required.
• Quality Concerns: With a 3.6/5 rating, some users report the hose is slightly shorter or the brass fitting may leak if overtightened. Use thread sealant (Teflon tape or pipe dope) on the fitting.
• Common Gotcha: The hose end cap (if included) can pop off under pressure. Secure it with a zip tie or replace with a brass plug for a permanent fix.
• Maintenance: After installation, test with a small amount of oil to check for leaks before filling the crankcase.

Should You Buy It

This is a solid budget pick if you’re tired of messy oil changes on a compatible Briggs & Stratton engine and don’t need OEM precision. It’s best for DIYers who don’t mind using thread sealant and maybe adding a zip tie for reliability. Skip it if you want a guaranteed leak-free fit or need a longer hose for hard-to-reach drains.
