Facet POSI-FLO Solid State Fuel Pump With POSI-FLO Technology
The Facet POSI-FLO Solid State Fuel Pump is designed for self-priming operation and vapor-lock elimination. It operates at 12V and provides a stable flow rate of 15 GPH with a 2 PSI max shutoff pressure. Its 1/8-27 internally threaded fitting makes it a direct OEM-style replacement for several Arrowhead models, including FPF-60304N. Best for: small to mid-size engines needing quick priming and reliable, quiet operation. Limitation: does not include a quiet valve, so noise levels may be higher than some aftermarket quiet designs.
Facet Solid State Fuel Pump (Arrowhead 40105N replacement)
Best for OEM replacement scenarios where a direct Arrowhead 40105N substitute is required. The 12V operation and standard fittings support straightforward installation. Limitations: this model’s data do not specify a quiet valve, so sound during operation may vary by vehicle mounting and fuel system layout.
Solid State Fuel Pump 12V, 17 GPH, 12″ Lift
This pump is designed for higher lift and consistent performance with a 12V supply and 15 GPH flow. It’s suitable for compact fuel systems needing an extended dry lift, up to 12 inches. Best for: installations requiring a balance of flow and lift. Caution: actual installed lift may depend on system layout and battery voltage under load.
Facet Solid State Fuel Pump – 40105
Facet’s 40105 model offers a compact, OEM-style form factor for straightforward swaps in compatible vehicles. It’s best for buyers seeking a simple, dependable replacement that matches factory dimensions. Limitation: the specific operating pressure and flow characteristics are not listed in the brief features, so verify compatibility with your fuel system constraints.
Facet-Purolator FPF-FEP42SV Solid State Fuel Pump Kit
The FPF-FEP42SV kit combines a solid state fuel pump with a 25 GPH rating and a flexible 1.5–4 psi operating range. It’s suitable for engines requiring a broader pressure window and higher flow than basic OEM replacements. Best for: more demanding fuel delivery needs or engines with tighter tolerances. Limitation: kit contents beyond the pump itself may require additional fittings or filters depending on the vehicle.
Buying Guide: Solid State Fuel Pumps
- Compatibility: Confirm OEM replacement compatibility with Arrowhead or Purolator part numbers. Match fittings (1/8-27 threads) and voltage (12V) to your vehicle’s electrical and fuel system.
- Flow vs. Pressure: Higher GPH pumps deliver more fuel but may raise pressure beyond what the engine requires. Choose a pump that aligns with your engine’s fuel demand and the pump’s max shutoff pressure.
- Self-Priming and Vapor Lock: Pumps featuring self-priming and vapor-lock elimination help when the vehicle experiences start-up delays or hot-start issues.
- Valves: Check valves improve reliability; quiet valves reduce noise. If noise is a primary concern, verify valve types in product specs.
- Installation Considerations: Some models include kit components; others require separate fittings or line adapters. Ensure clearance and mounting provisions in your engine compartment.
- Reliability and Warranty: One-year warranties provide coverage for replacement if the pump fails during normal use. Review warranty terms and claims process.
Frequently Asked Questions
- What is a solid state fuel pump?
A solid state fuel pump uses electronics to regulate fuel flow and pressure, often offering self-priming and vapor-lock prevention for more reliable starts. - Are OEM-replacement pumps compatible with older vehicles?
Yes, OEM-style replacements are designed to fit the original mounting and fittings when the specifications line up, such as voltage and thread size. - What is the benefit of a higher GPH rating?
A higher GPH rating delivers more fuel per hour, which is beneficial for higher-performance engines or when additional fuel delivery headroom is needed. - Do these pumps require special wiring?
Most solid state pumps operate at 12V and use standard ground and power leads, but always follow the vehicle’s wiring diagram for safe installation. - Can replacing a pump fix starting or vapor-lock issues?
Replacing a faulty pump can improve starting reliability and reduce vapor lock if the pump was not delivering adequate fuel pressure. - Is warranty important for fuel pumps?
A 1-year warranty provides assurance against manufacturing defects and helps with replacements if issues arise soon after installation.
