Facet Electric Fuel Pumps WITHOUT One-Way Check Valves

Fuel can flow backwards through these pumps when they are turned off

All of the Facet electrical fuel pumps listed here are built without a one-way check valve. A one-way check valve would prevent fuel from flowing backwards through the pump when it is turned off. Since these pumps do not have that valve, fuel can flow backwards through them.

One-way check valves are needed when running two pumps in parallel or when the fuel line makes a long uphill run from the tank to the engine. If your application does not have either of those conditions, you may be able to use a pump without a check valve.

Note that ALL Facet Dura-Lift series pumps are equipped with a one-way check valve.
