Product Description
Product Description
GRANATELLI 12V VACUUM SUPPORT SYSTEM
CAMMED. BOOSTED. ENGINE-SWAPPED. YOUR BRAKE BOOSTER STILL NEEDS VACUUM.
The Granatelli 410101B 12-Volt Electric Brake Vacuum Pump Kit provides supplemental vacuum for power brake boosters when engine vacuum is too low or inconsistent for dependable brake assist.
Designed for cammed vehicles, turbocharged and supercharged combinations, LS swaps, street rods and custom builds, the system automatically activates when vacuum drops and shuts itself off once the proper vacuum level is restored.
THE PROBLEM IT SOLVES
Low Engine Vacuum Can Reduce Brake Booster Assist
Cammed engines, forced-induction systems and certain modified engine combinations can produce less or less-consistent manifold vacuum, particularly at idle. The 410101B supplies vacuum independently of the engine to help maintain the vacuum reserve needed by a properly functioning power brake booster.
Automatic Vacuum — Only When the System Needs It
|
01
Vacuum DropsThe system monitors available vacuum in the circuit. |
02
Pump ActivatesThe 12V electric pump automatically begins restoring vacuum. |
03
Vacuum RestoredOnce the target level is restored, the pump automatically shuts off. |
IDEAL APPLICATIONS
Built for Vehicles That Don’t Produce Consistent Vacuum
● Cammed Vehicles ● LS Swaps ● Turbocharged Engines ● Supercharged Engines ● Street Rods ● Custom Builds ● Street / Race Applications
Why the Granatelli 410101B?
|
✓ 17–23 inHg Operating Range Designed to build and maintain supplemental vacuum within its intended operating range. |
✓ Automatic Self-Regulation Cycles on and off according to system vacuum rather than running continuously. |
|
✓ Quiet Isolated Motor Fully isolated motor assembly is designed to reduce operational noise and vibration. |
✓ Reinforced 3/8" Vacuum Hose Includes heavy-duty synthetic reinforced tubing with a 0.170" wall thickness. |
|
✓ EMI / RFI Protected Harness Fused wiring harness is designed for clean installation with reduced electrical interference. |
✓ Vibration-Isolated Mounting Mounting bracket helps isolate pump vibration from the vehicle. |
UNDERSTANDING THE 17–23 inHg RANGE
If It Cannot Reach or Hold Vacuum, Check the Entire System
The 410101B is designed to operate within approximately 17–23 inHg of vacuum. The pump should cycle as necessary to build and maintain vacuum within this range when connected to a properly sealed and functioning system.
If the system cannot reach or maintain the expected vacuum range, that does not automatically indicate a defective pump. Vacuum leaks, a leaking brake booster, faulty check valve, incorrect hose routing, loose fittings or other vehicle modifications can prevent the system from building or holding vacuum. Inspect the complete vacuum system before diagnosing the pump itself.
SMART VACUUM CONTROL
MAVP Sensor Control
Granatelli’s MAVP — Manifold Absolute Vacuum/Pressure — sensor monitors vacuum and controls pump operation without relying on a traditional vacuum-switch-and-relay arrangement, providing automatic control with a cleaner installation.

IMPORTANT VACUUM SYSTEM NOTE
The 410101B is designed to supplement a properly functioning vacuum system and operate within approximately 17–23 inHg. If the system cannot reach or hold the expected vacuum level, inspect the brake booster, check valve, vacuum hoses, fittings, routing and vehicle modifications for leaks or excessive vacuum demand before assuming the pump has failed.
