For moderate fuel requirements of engines up to about 150 horsepower, a single Solid State fuel pump is usually sufficient. 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. This complete kit includes Facet pump number 40289, mounting hardware, and a pair of adapters to accept your 5/16" fuel hose. Maximum fuel delivery 32 gallons per hour. Maximum pressure 4 to 7 psi. Typical flow 15 gallons per hour at 3 psi. 60" dry lift rating. 1/8 NPT female ports. This pump has a built-in check valve to ensure that fuel can only flow in one direction. It does not have an anti-siphon valve, so fuel can be pulled through when the pump is off. The negative lead has a ring terminal, and the positive lead is left bare.
