KEJSTED Fuel Injection Pressure Regulator Sensor for Ford Jaguar Lincoln — FPS7 Direct-Fit, Restores Fuel Rail Pressure & Drivabil

KEJSTED Fuel Injection Pressure Regulator Sensor (FPS7) is a direct-fit replacement sensor that monitors fuel rail pressure to help restore proper fuel delivery and drivability on compatible Ford, Lincoln, Jaguar and Mercury models.

This KEJSTED FPS7 fuel pressure sensor is designed as a vehicle-specific replacement for worn or failing original equipment sensors. It communicates rail pressure information to the engine control unit so the ECU can adjust fuel injector timing and pulse width. The result: improved control over fuel delivery, fewer fuel-related error codes, and smoother engine response when installed on supported engines that originally used the OE part numbers listed below.

How will this sensor affect my vehicle’s drivability?

Replacing a faulty fuel rail pressure sensor often eliminates symptoms caused by incorrect pressure readings. Expect crisper throttle response, fewer misfires, and a reduction in engine fault codes when the ECU can accurately monitor rail pressure. It does not change fuel type or engine tuning—only restores correct sensor input.

• Helps reduce rough idling and stalling related to bad pressure readings
• Improves acceleration consistency by providing accurate rail pressure data
• Can clear or prevent fuel-system related engine warning lights

Which vehicles and OE numbers is this compatible with?

The KEJSTED FPS7 is compatible with a broad list of Ford, Lincoln, Mercury and Jaguar models that used the original sensor types. Verify fitment against your VIN and the OE numbers to ensure a correct match before purchasing. The listing includes many common part numbers and model years for quick cross-reference.

• Fits models such as Ford E-150, F-150, Explorer, Taurus; Lincoln LS, Town Car; Mercury Tracer and more
• Replaces OE numbers like 3R3E-9F972-AA, FPS7, FPS-17, SU10479 and many cross-reference codes
• Check the part connector and mounting style pictured to confirm compatibility

Is installation difficult and what tools are required?

Installation is straightforward for anyone comfortable working under the hood and removing a small sensor from the fuel rail. Basic hand tools and safety precautions—relieving fuel pressure and disconnecting the battery—are typically required. Many owners perform this swap themselves in under an hour.

• Basic socket set and pliers for connector removal
• Fuel-pressure relief procedure and shop rags to catch minor drips
• Reconnect battery and clear codes after installation, or use a scanner

What quality checks and support come with the sensor?

KEJSTED sensors undergo strict quality inspections before shipping to reduce DOA rates and poor-fit issues. The unit is built with sealing and durable materials to withstand typical under-hood conditions. If you receive a defective part, KEJSTED provides replacement or refund support within their specified response window.

• 100% quality-tested prior to shipment
• Durable construction and sealing for long-term use
• Customer support available for replacement or refund on failures

Who is this for: The KEJSTED Fuel Injection Pressure Regulator Sensor FPS7 is intended for DIY mechanics, independent shops, and fleet technicians who need an OE-style replacement for fuel rail pressure sensing on supported Ford, Lincoln, Mercury and Jaguar models. Confirm part numbers and connector style before ordering to ensure a correct, hassle-free swap.
