Facet fuel pumps have low power requirements (about 1 amp at 12 volts) and operate without troublesome seals or diaphragms. Built-in pressure relief means no flooding after shutting down a hot engine. Facet pumps are compatible with gasoline, alcohol blends (up to and including E85), diesel, biodiesel, and fuel additives.
Maximum fuel delivery 34 gallons per hour. Maximum pressure 4 to 5 psi. Typical flow 23 gallons per hour at 2 psi. 1/8 NPT female ports. Negative ground (12v) only. This pump features an anti-siphon valve to prevent the tank from draining when the pump is turned off. This pump does not have an internal filter. Also features a unique offset mount (see photo).
Facet part number 40133(E)*. This pump was standard equipment on some models of Onan RV generators (Cummins / Onan part number 0149-1919). Also replaces Onan part number 0149-1994 and 0149-2110. The built-in anti-siphon valve prevents fuel from being pulled through when the pump is turned off. This makes it ideal for applications where the generator is mounted some distance from the fuel tank, or the carburetor is lower than the tank.
* Note: The Facet “Interruptor” style pumps now feature reliable solid-state technology instead of points! The "E" stands for "Electronic".
Beware of counterfeits! We only sell Genuine Facet pumps - not the unreliable foreign knock-offs sold elsewhere. Facet pumps are still Made in the USA.
