1930 Demon Accelerator Pump Check Valve

A carburetor company’s standing is revealed by its reputation for innovation, its record of success, and how easy it is to deal with.

When the range of four-barrel modular carburetors from Demon first burst onto the scene in the late 1990s, it acquired a meteoric reputation for innovation.

Noticeable was its uniquely attractive appearance with beautifully contoured air entries and shapely fuel bowls.

This, coupled with its vast array of ground-breaking features, set it apart.

To eradicate internal porosity, Demon introduced billet metering blocks and base plates.

To eliminate impediments to air flow, Demon initiated ridge-free concentric venturii.

To overcome the dangers of fuel contacting hot exhausts during float-level checks, large capacity fuel bowls with sight glasses were instigated by Demon.

To nourish the ambitions of adventurous tuners, interchangeable venturii, idle-feed restrictors, and air bleeds were invented by Demon.

Of its type, these remain today the most potent carburetors ever devised.

Innovation from Demon has not been confined to the enduring modular four-barrel configuration.

In the early years of this century, the unique SixShooter induction system was launched by Demon Carburetion, and in 2008, the evocative Demon 98 was introduced.

A wonderfully nostalgic arrangement featuring three two-barrel 250cfm carburetors mounted on a proprietary intake manifold, the SixShooter fuels small- and big-block Chevrolets as well as LS engines, small-block Fords, and some Pontiacs.
