Key specs for this pump

Model 311553GS

This identifier ensures you order the exact replacement part for your specific pressure washer. Using the correct model number prevents fitment issues and ensures compatibility with your existing machine. Always verify this code against your current pump before purchasing to avoid returns or installation delays.

Weight 6.42 pounds

This mass indicates a standard replacement unit that is manageable for most DIY installers. It is light enough to handle easily but substantial enough to feel durable. When comparing pumps, this weight helps you gauge if the new unit fits your machine's mounting points and load requirements.

Length 12.4 inches

This dimension defines the horizontal space the pump occupies on your pressure washer chassis. You need this measurement to ensure the new pump fits within your machine's frame without interfering with hoses or other components. Compare this length with your old pump to confirm spatial compatibility.

Width 10.4 inches

This measurement specifies the side-to-side footprint of the pump. It is critical for checking clearance against adjacent parts of your pressure washer. A wider pump might not fit in tight spaces. Ensure this width aligns with your machine's design to avoid modification needs during installation.

Height 9.28 inches

This vertical measurement determines how much clearance is needed above the pump. It affects how hoses and fittings connect without bending too sharply. Check this height against your current setup to ensure all connections remain accessible and functional after installation. Proper clearance prevents strain on your plumbing.

Design and build quality

The listing describes this unit as a genuine Briggs & Stratton pump, finished in black. This color choice is practical for a replacement part, as it helps the component blend with existing machinery rather than standing out visually. You are getting a unit designed specifically to fit into your current pressure washer setup without requiring aesthetic compromises.

According to the listing, the physical dimensions are 12.4 inches in length, 10.4 inches in width, and 9.28 inches in height. These measurements define the space you need to allocate during installation. You should verify that your pressure washer frame can accommodate this specific footprint. The layout is compact, which is typical for replacement pumps that must fit into confined engine compartments or chassis structures.

The weight is listed at 6.42 pounds. This mass is substantial enough to provide stability during operation but light enough to handle during a swap. You do not need heavy lifting equipment to install this part. The combination of these dimensions and this weight suggests a design focused on direct replacement rather than new feature integration. You are essentially restoring the original mechanical configuration of your machine. The black finish offers a uniform look, ensuring the new pump matches the rest of your equipment's exterior.
