Direct Injection Fuel Pump Overview

Spectra FI1555 is a direct injection high pressure fuel pump built to maintain steady fuel pressure for stable combustion across low and high engine speeds. It is a fitment-based replacement for select Hyundai and Kia applications, including Hyundai Sonata, Santa Fe Sport, and Kia Optima, Sportage, and Sorento.

Key Features

• Direct injection high pressure fuel pump for gasoline direct injection systems
• Supports consistent operating pressure for smoother fuel delivery
• Helps promote efficient engine operation across a wide speed range
• Engineered to reduce negative impact on the engine and fuel system

The FI1555 is a practical choice when you need a direct injection high pressure fuel pump that matches the original application and supports stable combustion under changing engine loads.

Common Problems It Can Address

• Hard starting caused by insufficient high-pressure fuel delivery
• Rough idle related to unstable fuel pressure
• Loss of power during acceleration from inconsistent injection pressure
• Fuel economy decline tied to poor fuel system performance
• Increased emissions from uneven combustion

Installation Notes

Verify the vehicle year, make, model, and engine application before ordering. Confirm the direct injection fuel system configuration and compare the original part number FI1555 against the removed pump. Professional installation is recommended for high-pressure fuel system components, and the fuel system should be inspected for contamination or related wear during replacement.
