CII Power Steering Pump Replacement For Ford, Mercury, Lincoln, and Mazda Vehicles - Single Return Line Reservoir, 1450PSI / 2.75GPM, 16x1.5MM Hose Type

Frequently Asked Questions

What vehicles does this pump fit?

This pump is designed as a direct bolt-in replacement for many Ford, Lincoln, and Mercury vehicles equipped with a Ford CII power steering pump and a 5/8-18 SAE inverted flare pressure hose connection. Please verify your application using the fitment chart before ordering.

What makes this pump different from a remanufactured Ford CII pump?

Unlike most replacement pumps, this unit is built with all-new components and uses Lee Power Steering's proprietary Saginaw-style internal rotor and vane design. The result is improved durability, quieter operation, better low-RPM performance, and increased fluid flow compared to the original Ford CII pump design.

Why is the Lee CII pump quieter than the stock Ford pump?

The original Ford CII pumps are known for their whining noise. Lee's redesigned pump uses Saginaw-style internals with a more efficient rotor and vane arrangement that reduces noise, improves fluid movement, and decreases wear.

Is this pump intended for a steering gearbox or rack-and-pinion system?

This version is specifically configured for steering gearbox applications and is calibrated to 1450 PSI and 2.75 GPM. These settings are generally better suited for gearbox-equipped vehicles than rack-and-pinion systems.

What pressure hose fitting does this pump use?

This model uses a 5/8-18 SAE inverted flare pressure outlet fitting. Be sure your vehicle's pressure hose matches this connection type before ordering.

Does this pump have a single or dual return reservoir?

This pump features a single-return reservoir designed for vehicles that do not use hydroboost brakes. Vehicles equipped with hydroboost typically require a dual-return reservoir.

Can this pump be used with hydroboost brakes?

No. This specific version is not intended for hydroboost applications. If your vehicle uses hydroboost brakes, we recommend one of our dual-return CII pump configurations.

Can I customize the pressure and flow settings?

Yes. All Lee CII pumps can be custom configured with specific pressure, flow, reservoir style, and hose fitting options to match your application.

Is this a brand-new pump?

Yes. Every Lee CII pump is assembled using new components and is tested in-house at our Valencia, California facility before shipment. It is not a rebuilt or remanufactured unit.

Will this pump help improve steering performance?

Many customers experience smoother steering response, reduced steering effort at low speeds, quieter operation, and improved reliability compared to factory replacement pumps. The improved internal design provides more consistent hydraulic flow, particularly at lower engine speeds.

Can larger tires affect the power steering pump requirements?

Yes. Larger tires generally require higher steering effort, which can influence the ideal pressure and flow settings. If your vehicle has oversized tires, contact us for recommendations on the best pump configuration.

My power steering pump is noisy. Is the pump always the problem?

Not necessarily. Air in the system, improperly bled steering components, leaking hoses, worn gearboxes, hydroboost units, or poorly designed reservoirs can all create noise. Before replacing a pump, it is important to inspect the entire steering system.

Where is this pump built and tested?

Each pump is hand-assembled and tested by Lee Power Steering in Valencia, California before it leaves our facility.

What should I do if I'm unsure which CII pump I need?

Contact our technical support team with your vehicle year, make, model, engine, steering system type (gearbox or rack-and-pinion), brake system type (vacuum or hydroboost), and hose fitting information. We'll help you select the correct pump for your application.

What vehicles is this pump designed for?

This pump is a direct bolt-in replacement for many Ford, Mercury, Lincoln, and Mazda vehicles originally equipped with a Ford CII power steering pump using a 16x1.5mm metric pressure hose fitting. Always verify your vehicle against the fitment chart before ordering.

What pressure and flow settings does this pump use?

This pump is configured with 1450 PSI pressure and 2.75 GPM flow, making it ideal for steering gearbox applications.

What hose fitting does this pump use?

This version uses a 16x1.5mm metric pressure outlet fitting. If your vehicle uses a 5/8-18 SAE inverted flare hose, you'll need the SAE version instead.

What makes this pump better than a stock Ford CII pump?

Lee Power Steering redesigned the CII pump using Saginaw-style internals, including a different rotor, ring, and vane design. This produces more efficient fluid flow, quieter operation, and improved steering performance compared to the original Ford pump design.

Why is this pump quieter than other replacement pumps?

The original Ford CII pump is known for noise and whining. The Lee CII replacement uses a Saginaw-style rotor and vane arrangement that moves more fluid per revolution and reduces cavitation, resulting in significantly quieter operation.

Is this pump new or remanufactured?

This is a brand-new pump, not a rebuilt or remanufactured unit. Every pump is hand-assembled using new components and tested at Lee Power Steering's California facility before shipping.

Is this pump intended for hydroboost brake systems?

No. This version uses a single-return reservoir and is intended for vehicles without hydroboost brakes. Vehicles equipped with hydroboost typically require a dual-return reservoir pump.

Can this pump be used with rack-and-pinion steering?

This specific model is calibrated for steering gearbox applications. Rack-and-pinion systems generally require different pressure and flow settings, and Lee offers dedicated rack-and-pinion versions for those applications.

Can I order this pump with custom pressure and flow settings?

Yes. Lee Power Steering can custom configure CII pumps with different pressure settings, flow rates, reservoir styles, and hose fitting options to match your application.

Will this pump improve steering feel?

Many customers report smoother steering response, lighter steering effort at low speeds, and quieter operation compared to factory replacement pumps. The improved internal design helps provide more consistent hydraulic performance.

Why does this pump cost more than a remanufactured replacement?

Unlike most remanufactured pumps, this unit is built with all-new components, upgraded internals, and is individually assembled and tested. The improved performance, durability, and noise reduction justify the investment for customers seeking a long-term solution.

My power steering pump is noisy. Will replacing it solve the problem?

Not always. Air entering the system through hoses, worn steering gears, hydroboost units, or poorly designed reservoirs can also cause noise. It's important to inspect the entire steering system before replacing components.

What are the signs of a failing CII power steering pump?

Common symptoms include:

• Steering whine or groaning noises
• Increased steering effort

Inconsistent steering assist

• Fluid leaks
• Foamy or aerated power steering fluid

If you're experiencing these symptoms, a replacement pump may be needed.

Where is this pump built?

Each pump is hand-assembled and tested by Lee Power Steering in Valencia, California, using new components and upgraded internal parts.

How can I verify I am ordering the correct pump?

Check the following before ordering:

• Vehicle year, make, and model
• Gearbox or rack-and-pinion steering
• Hydroboost or vacuum brake system
• Pressure hose fitting type (16x1.5mm Metric or 5/8-18 SAE)
• Reservoir style requirements

If you're unsure, contact Lee Power Steering and we'll help identify the correct pump for your application.

What fluid should I use?

Lee Power Steering Fluid is strongly recommended for maximum pump life and reduced foaming.

Acceptable alternatives include:

• AC Delco non-synthetic power steering fluid
• Valvoline non-synthetic power steering fluid

Do NOT use:

• ATF
• Synthetic power steering fluid
