Review: 03 Expedition fuel pump relay - Ran a wire from the positive on battery to the 4 pin connector which I unplugged.. stuck it in the slot with the green wire with yellow stripe. 4x4 lights blinked the whole way home however it got me home when I was stranded. Good way to diagnose a relay problem before you remove the gas tank for no reason. Be sure to order a fuel filter with this! as it is usually caused by either a clogged filter or a fuel pump that is going bad and getting over worked. 2003 expedition eddie bauer 5.4L Review: Great replacment for 2004 Expedtion 5.4L Eddie Bauer. - This relay was exactly what I needed. I was having stalling issues and no check engine light. I took the rig to my mechanic who has a very expensive scan tool. He was able to pull a memory code of P0231. I was able to solder this relay into the circuit board of the central junction box (fuse block), saving the $400 not buying a new fuse block. Getting the fuse box out of the car and disassembled to remove the circuit board was more work than removing and re soldering in this relay. I am happy I chose to do this repair myself as it was very cheap, pretty easy, and only took 1.5 hours. Youtube is a great source for how to video. ## Features - R303 - 12V Replaces Omron Relay F8VF-BA - Coil Voltage: 12 VDC - Contact Form: SPDT (1 Form C) - Contact Material: Silver Tin Oxide (AgSnO) - Mounting Style: Through Hole ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079QVDRGZ | | Best Sellers Rank | #1,012,119 in Automotive ( See Top 100 in Automotive ) #204 in Automotive Replacement Fuel Pump Relays | | Brand Name | Omron | | Coil Voltage | 12 Volts | | Connector Type | Through Hole | | Contact Material | Silver Tin Oxide | | Contact Type | Normally Open | | Customer Reviews | 4.5 4.5 out of 5 stars (109) | | Manufacturer | Omron Automotive Relay | | Maximum Switching Voltage | 12 Volts | | Minimum Switching Voltage | 12 Volts (DC) | | Mounting Type | Through Hole Mount | | Number of Terminals | 3 | | Operation Mode | Automatic | | Part Number | F8VF-BA (Pack of 1) | | Wattage | 685 Milliwatts | ## Product Details - **Brand:** Omron - **Connector Type:** Through Hole - **Contact Material:** Silver Tin Oxide - **Contact Type:** Normally Open - **Mounting Type:** Through Hole Mount ## Images ![OMRON Fuel Pump Relay R303-12V Replaces Omron Relay F8VF-BA - Image 1](https://m.media-amazon.com/images/I/71dr6De3ENL.jpg) ![OMRON Fuel Pump Relay R303-12V Replaces Omron Relay F8VF-BA - Image 2](https://m.media-amazon.com/images/I/71PeEpaInGL.jpg) ![OMRON Fuel Pump Relay R303-12V Replaces Omron Relay F8VF-BA - Image 3](https://m.media-amazon.com/images/I/81xyezkoPVL.jpg) ![OMRON Fuel Pump Relay R303-12V Replaces Omron Relay F8VF-BA - Image 4](https://m.media-amazon.com/images/I/61RAXCYuQ+L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 03 Expedition fuel pump relay *by R***N on September 6, 2022* Ran a wire from the positive on battery to the 4 pin connector which I unplugged.. stuck it in the slot with the green wire with yellow stripe. 4x4 lights blinked the whole way home however it got me home when I was stranded.
