793147 Fuel Pump Vacuum Hose 4 Pack, Replacement for Briggs & Stratton 401000 405000 406000 John Deere LA130 LA135 D110, Synthetic Rubber Vacuum Line for Lawn Mower Small Engine

What It Is

This is a 4-pack of synthetic rubber vacuum hoses designed to replace the fuel pump vacuum line on small engines, primarily Briggs & Stratton models 401000, 405000, and 406000, as well as John Deere lawn tractors like the LA130, LA135, and D110. It restores fuel delivery by connecting the fuel pump to the crankcase or carburetor.

Fitment & Compatibility

Before buying, confirm your engine model number (e.g., 401000 series) and mower brand. This hose fits Briggs & Stratton engines using a 3/16-inch inner diameter vacuum line. Check your original hose length—these are pre-cut to about 6 inches each, so they suit short runs. For John Deere models, verify you have a Briggs engine, not a Kawasaki or Kohler. Measure the nipple diameter on your fuel pump and crankcase port; if it’s 1/4-inch or larger, these won’t seal. OEM part cross-references include Briggs & Stratton 793147, 691043, and 692510.

Key Things to Buy

• Quality: Synthetic rubber resists fuel and heat better than standard vinyl, but these are still thin-walled—avoid sharp bends or kinks during installation.
• Installation: Simple DIY job. Use a small pick to remove the old hose, push the new one on until snug, and secure with zip ties or clamps if the fit feels loose (common on worn nipples).
• Gotcha: These are not fuel line—they’re vacuum line. Do not use them for pressurized fuel delivery between the tank and carburetor. Also, the 4-pack is handy for spares, but you only need one hose per engine.
• Check condition: If your old hose is cracked or collapsed, replace it immediately. A vacuum leak here causes hard starting, stalling, or low power.

Should You Buy It

If you own a Briggs & Stratton 401000-406000 engine or a compatible John Deere lawn tractor and need a quick, cheap fix for a vacuum line issue, this pack is a solid value. It’s ideal for routine maintenance or replacing a brittle hose, but skip it if you need a longer length (over 8 inches) or a thicker wall for high-vibration engines.
