HONGYETAJA Fuel Pump Relay NEC/Tokin EX1-1F1J 12V Automatic 30A

Description

Product Overview

The HONGYETAJA NEC/Tokin EX1-1F1J fuel pump relay is engineered to meet the rigorous demands of modern automotive fuel systems. Built around a 36‑volt coil that operates at 900 milliwatts, the relay delivers a steady 30 ampere switching current, providing the precise control needed for reliable fuel pump operation. Its plug‑in mounting type simplifies installation, allowing technicians to replace the unit without soldering or extensive disassembly. The contact material, silver tin oxide, offers superior conductivity and resistance to corrosion, ensuring long‑term performance even in high‑temperature environments up to 125 °C. With a compact package measuring just 2.6 × 1.02 × 0.75 inches and a lightweight design of 0.423 ounces, the relay fits seamlessly into the limited space of the TIPM‑7 fuse box found in many 2007‑2020 Chrysler, Dodge, Jeep and Volkswagen vehicles. The device complies with automotive standards for soldered specifications and carries the UPC 610877970001, confirming its authenticity and traceability. Designed for automatic operation, the relay closes the circuit when the engine control module signals fuel pump activation, and opens it when the pump is not required, reducing unnecessary wear and improving overall fuel efficiency.

Usage

This relay is a direct replacement for part numbers EX1‑2U1S, EX1‑2U1, and EX1‑2U1L, making it an ideal solution for owners experiencing fuel pump relay failures, no‑start conditions, or intermittent stalling. It is particularly suited for vehicles equipped with a Totally Integrated Power Module (TIPM) where the relay is soldered onto one of six circuit boards. By swapping the original unit with the HONGYETAJA relay, drivers can restore proper fuel flow without the need for extensive rewiring. The plug‑in design means the relay can be installed in a matter of minutes, reducing vehicle downtime. It is compatible with a wide range of models, including the Chrysler Ram, Caravan, Town & Country, Routan, Durango, Grand Cherokee, as well as Dodge and VW platforms that share the same electrical architecture. Whether the vehicle is used for daily commuting, long‑distance travel, or off‑road adventures, the relay’s robust construction ensures consistent performance across diverse operating conditions. Regular maintenance checks should include inspection of the relay’s contacts for signs of wear, but the silver tin oxide coating greatly extends service intervals compared to standard copper contacts.
