Product Description
The 28146 12V electric vacuum pump is essential for vehicles where engine vacuum is too low for optimal brake booster performance. This automatic vacuum pump activates when vacuum drops below 18 inHg and shuts off at 22 inHg, ensuring consistent braking force. Made from durable aluminum, it reduces vibration and operates quietly (≤65dB).
This brake booster vacuum pump is ideal for Hot Rods, Chevy, Ford, and Mopar vehicles with aggressive camshafts or modified engines. The kit includes pre-wired connections for hassle-free installation, making it a top choice for auto repair shops and performance part distributors.
Key applications:
✔ Restores braking power in low-vacuum engines
✔ Self-regulating switch for efficient operation
✔ Compatible with GM, Ford, and Mopar models
✔ Bulk order discounts for wholesale auto parts suppliers
