Johnson Pump Viking Power 32 Vacuum Pump - 6.3GPM - 12V

The Johnson Pump Viking Power 32 Vacuum Pump – 6.3GPM – 12V is a compact, electrically driven vacuum source engineered for custom automotive applications where traditional engine-driven systems aren't feasible or desired. Whether you're running a carbureted hot rod, building a custom brake booster setup, or integrating vacuum-dependent emissions controls into a modified engine bay, this pump delivers reliable suction without parasitic load on your engine. It's become a go-to choice for fabricators and weekend warriors who need independence from belt-drive constraints and want precise control over vacuum availability.

Built by Johnson Pump, a respected manufacturer of marine and automotive fluid systems, the Viking Power 32 operates on 12-volt DC power and generates 6.3 gallons per minute of vacuum flow—sufficient for fuel pressure regulators, brake boosters, HVAC servos, and emission control devices on vehicles ranging from classic restorations to modern engine swaps. The pump's compact footprint (11 x 8 x 12 inches) and modest 12.9-pound weight make it easy to mount under a dash, in a fender well, or under-bed in tight engine compartments. The unit's sealed brushless design minimizes maintenance and extends service life in dusty or vibration-prone environments common to off-road and modified vehicles.

Mechanics and custom fabricators favor this pump for engine swaps where the original block doesn't provide vacuum ports, or when OEM vacuum-dependent systems must function independently of engine modifications. It pairs well with aftermarket carburetors, manual brake-to-power-brake conversions, and complex custom fuel delivery systems. Installation requires only basic 12V wiring to a fused circuit and hard line or hose connections to your vacuum distribution block. The pump's quiet operation and reliable 12V duty cycle make it ideal for show cars, street rods, and off-road vehicles where consistent vacuum control enhances drivability and component longevity.
