Full details

The NGK Solid State Fuel Pump (40105) is an essential component for automotive enthusiasts and professionals working on vehicles that require a reliable, consistent fuel delivery system. Designed for cars, vans, RVs, and light trucks, this pump excels in low-to-high-pressure carburetor applications by providing a steady 3.0-4.5 PSI flow. While it offers impressive versatility with various fuel types, users should ensure their specific engine requirements align with the fixed pressure output before installation.

FAQs

Can I use this pump for fuel-injected engines?

No, this pump provides 3.0-4.5 PSI, which is intended for carburetor applications. Most fuel injection systems require significantly higher pressure.

Is this pump suitable for E85 or alcohol-blended fuels?

Yes, the materials used in the construction of the 40105 are compatible with blended alcohol fuels.

What is the maximum dry lift of this pump?

The pump has a dry lift capacity of 120 inches.

Does this pump require a fuel pressure regulator?

If your carburetor requires a pressure lower than 3.0 PSI, you may need an external regulator, but it is not required for most standard applications.

Can this pump be mounted in any orientation?

While the pump is flexible, it is generally recommended to mount it vertically to ensure optimal operation of the internal check valves.

Troubleshooting

Pump fails to prime

Check fuel lines for air leaks and ensure the fuel level in the tank is sufficient to reach the inlet.

Engine is starving for fuel

Inspect the pre-pump fuel filter for clogs and verify that the electrical voltage at the pump terminals is a steady 12v.

Leaking at the fittings

Ensure that the correct NPT thread sealant was used and that the fittings are tightened to the appropriate torque without over-stressing the housing.

Pros and Cons

Pros

Compatible with a wide array of fuel types including biodiesel and alcohol blends
Strong dry lift capacity simplifies installation location
Solid-state construction increases longevity and reliability
Sufficient flow rate for most standard carburetor setups

Cons

Fixed pressure range may not be suitable for fuel injection systems
Requires proper NPT fitting sealant to prevent leaks
Lacks an internal shut-off switch for safety in collision scenarios

Setup, Compatibility & Care

For installation, ensure the pump is mounted in a location protected from excessive heat and road debris. Use high-quality thread sealant on the 1/8th nptf fittings to ensure a leak-free connection. Because this pump is designed for 12v systems, always verify your vehicle's wiring voltage before connection. To maintain the pump, periodically check fuel filters upstream to prevent debris from entering the pump housing. The solid-state nature of the device requires minimal maintenance beyond ensuring the electrical connections remain tight and free of corrosion.
