• Vacuum Output: Ensure the pump produces enough vacuum (typically 18–25 inches) for your vehicle's brake booster to function properly.
• Compatibility & Fit: Match the pump voltage (usually 12V) and mounting style to your car. Check for vehicle-specific fitment for direct replacement.
• Noise Level: Rotary vane pumps tend to be quieter than piston-style models, which can be a big comfort factor during daily driving.
• Auto Cycling: Pumps with an integrated vacuum switch cycle on/off automatically, reducing continuous running and saving energy.
• Installation Kit: Look for kits that include wiring, tubing, and mounting hardware for a straightforward installation without extra purchases.
