To mount a Facet fuel pump, position it at a 45-degree angle to completely vertical with the outlet facing upwards.
Proper mounting is crucial for the efficient operation and longevity of your Facet fuel pump, especially in gasoline installations. The recommended mounting orientation helps prevent issues like vapor lock.
Based on the manufacturer's guidelines:
- Angle: The pump should be mounted at an angle ranging from 45 degrees to a completely vertical (90 degrees) position.
- Orientation: The pump's outlet must be higher than its inlet.
Why This Mounting Position is Recommended
Mounting the pump with the outlet higher than the inlet, specifically at a 45-degree to completely vertical position, is particularly beneficial in gasoline setups under hot conditions. This orientation helps air and fuel vapor rise through the pump and be purged towards the engine, significantly reducing the risk of vapor lock. Vapor lock occurs when liquid fuel turns into a gas while still in the fuel line, obstructing flow and preventing the engine from starting or running smoothly.
By adhering to these mounting specifications, you ensure the pump can effectively prime itself and maintain a consistent fuel supply, even in challenging environments.
