Solid-state Facet cube-style fuel pumps have low power requirements (about 1 amp at 12 volts) and operate without troublesome seals or diaphragms. Facet pumps are compatible with gasoline, alcohol blends (up to and including E85), diesel, biodiesel, and fuel additives. This model is rated for maximum fuel delivery of 50 gallons per hour at free-flow. Maximum pressure 12 to 15 psi. Typical flow 30 GPH at 5 psi or 20 GPH at 8 psi. 1/8 NPT female ports. This pump has an internal one-way (anti-drainback) check valve to prevent fuel from draining backwards through the pump. It does not have a positive shut-off (anti-siphon) valve, so fuel can flow through the pump when turned off. The huge 96 inch dry lift capability is greater than any other cube-style pump Facet offers. The positive and negative wires have a 2-pin Amp connector installed from the factory. This model is sold under Kohler part numbers 6585163, 6585005S, 6585008S, and 6585170S; and Polaris part numbers 8450172 and 8450180. This pump can also replace Facet pump number 40277 and 40299 (exactly the same specifications, except this pump has an Amp connector instead of a Packard or Deutsch connector).
