LOCOPOW Fuel Pump Replacement for Briggs & Stratton 844527/844089 — 1/4" Vacuum Pump, Low-Pressure Diaphragm

LOCOPOW Fuel Pump Replacement is a direct-fit vacuum-style fuel pump designed to replace Briggs & Stratton parts 844527 and 844089, restoring reliable fuel delivery for compatible small engines.

If your lawn mower, generator, or other small engine is stalling, hard to start, or running unevenly because the original fuel pump has failed, this LOCOPOW replacement offers an affordable, brand-new option. Constructed as a vacuum-type pump with 1/4" fuel inlet and outlet fittings, it fits applications that used the B&S 844527 / 844089 units and is built for conventional gasoline blends (not for fuels with more than 10% ethanol).

How will this LOCOPOW pump restore engine performance?

Replacing a worn or leaky fuel pump reestablishes consistent fuel flow and proper carburetor priming, which helps eliminate rough idling and frequent stalling. This LOCOPOW piece restores the vacuum-actuated delivery mechanism that many older small engines rely on.

• Direct replacement for B&S 844527 and 844089 mounting and hose size.
• Vacuum-operated diaphragm design for steady low-pressure fuel delivery.
• 1/4" inlet/outlet to match common small engine fuel lines.
• New, unused component to prevent wear-related leaks and performance loss.

Will it fit my machine and how do I confirm compatibility?

This unit was manufactured to match the form and fittings of the referenced Briggs & Stratton parts, so fitment is straightforward when your original pump uses a 1/4" vacuum-style connection and the same mounting layout. Always compare the part numbers and physical dimensions before installation.

• Check that your old pump is labeled 844527 or 844089, or matches their shape and hose size.
• Verify fuel line diameter is 1/4" for both inlet and outlet connections.
• Confirm the pump is used in engines tolerating low ethanol content (under 10%).
• Measure mounting holes and bracket alignment for a trouble-free swap.

What are the installation and handling tips for this fuel pump?

Installation generally requires basic hand tools and a careful approach to fuel system safety: work in a well-ventilated area, disconnect the spark plug, and relieve fuel pressure before removing old hoses. Reinstall new clamps and inspect for leaks after starting the engine.

• Disconnect spark and drain or clamp fuel line to avoid spills.
• Replace old hose clamps and use fresh fuel-rated tubing if needed.
• Start the engine and check joints for leaks; tighten clamps as required.
• Do not use with fuels containing more than 10% ethanol to avoid premature degradation.

What materials and quality assurances does LOCOPOW provide?

This pump ships brand-new and unused, built to meet replacement specifications and backed by LOCOPOW after-sales support. The design focuses on durability for typical outdoor equipment use and includes quality checks before dispatch.

• 100% new condition, never used or refurbished.
• Manufactured for consistent vacuum-diaphragm operation.
• Quality control inspection and customer support for post-purchase issues.
• Intended for standard gasoline blends, excluding fuels above 10% ethanol.

Who is this for? If you own small gas-powered equipment—such as lawn mowers, pressure washers, generators, or garden tractors—that originally used Briggs & Stratton fuel pumps 844527 or 844089, and you need a straightforward replacement that matches mounting and hose fittings, this LOCOPOW vacuum-type pump is a practical solution. It's suited for DIY installers and professional technicians seeking a new, reliable unit for engines compatible with low-ethanol gasoline.
