EZJOB Pressure Washer Pump Replacement 7/8" Vertical Shaft Front Outlet — 2400–2800 PSI, 2.5 GPM

Replacement pressure-washer pump for front-outlet gas units delivering up to 2800 PSI and 2.5 GPM with a 7/8" vertical shaft.

This EZJOB pump is a direct-fit aftermarket unit designed for many 4–7 HP vertical-shaft gas pressure washers that originally used a front-facing hose connection. It comes pre-filled with oil and includes common installation hardware so you can swap it in quickly when your original pump leaks, fails to build pressure, or pulses. Before ordering, measure key dimensions—shaft diameter and length, keyway position, mounting hole spacing, and pump height—to confirm compatibility with your machine.

How will this pump restore cleaning performance?

When a worn pump can’t hold pressure or delivers inconsistent flow, replacing it with a correctly rated unit brings pressure and volume back to working levels. This EZJOB pump is rated to restore up to 2800 PSI and provides up to 2.5 gallons per minute for standard cleaning tasks.

• Maximum pressure: 2800 PSI to match higher-output gas models
• Flow rate: up to 2.5 GPM for typical detergent and rinsing cycles
• Designed footprint and mounting for many 4–7 HP, 196–224cc engines
• Front-facing inlet/outlet to match front-connection pressure washers

What installation parts and protections are included?

The pump ships pre-filled with oil and includes a shaft key and common fittings to simplify the swap. Built-in safety and convenience features help protect the pump and engine during normal use.

• Pre-filled crankcase oil for immediate operation
• Included shaft key for secure coupling to the engine
• Easy Start (EZ) valve, thermal relief valve and unloader for protection
• M22 high-pressure outlet and 3/4" NH copper nut inlet with SAE flange

Which machines will this pump fit and how do I verify fitment?

This pump is intended for select gas pressure washers with vertical 7/8" shafts and forward-facing hose ports. Compatibility is determined by engine size range, shaft details and pump mounting geometry rather than brand alone.

• Intended engine range: 4–7 HP, 196–224cc (vertical-shaft engines)
• Shaft: 7/8" diameter vertical shaft—confirm length and keyway location
• Pressure range: 2400–2800 PSI models (verify desired PSI matches your wand/nozzle)
• Check mounting holes and pump height to ensure proper fit

How does the front-outlet layout affect hose routing and storage?

A forward-facing inlet and high-pressure outlet make hose and garden-hose connections more accessible on pressure washers built for front access. That layout can simplify setup, reduce hose bends, and make storage neater on small units and carts.

• Front ports keep hoses clear of engine and frame obstructions
• Improved accessibility for quick hook-up and breakdown
• Ideal for machines originally designed with front hose access
• Reduces awkward hose routing on compact pressure washer frames

Who is this for: This EZJOB 7/8" front-outlet replacement pump is for DIYers and service technicians who need a drop-in solution for select 4–7 HP vertical-shaft gas pressure washers that require a front-facing inlet/outlet. Choose this pump if your original unit leaks, fails to build or hold pressure, or pulses under load—and only after confirming shaft size, keyway, mounting dimensions and desired PSI/GPM ratings match your machine.
