* Size and Shape: It's generally a small, rectangular component, often about the size of a pack of chewing gum or slightly larger.
* Housing: The housing is usually made of plastic, typically black or dark gray.
* Terminals: It will have several terminals or pins (usually 4 or 5) sticking out from the top or side, for electrical connections. These terminals are often numbered or lettered.
* Possible markings: It may have markings indicating its function (e.g., "FUEL PUMP," or a part number) or voltage rating. Some relays might have a click-clack sound when activated.
* Internal components: While you won't see these without opening it (which is generally not recommended), inside is typically an electromagnetic switch controlled by a small coil of wire.
To find yours, you'll need to:
1. Consult your vehicle's repair manual: This is the best resource to identify the exact location and appearance of your fuel pump relay.
2. Search online: A Google image search using terms like "[Your car make and model] fuel pump relay" can show you what it might look like in your specific vehicle.
3. Check your fuse box: Fuel pump relays are often found in fuse boxes, usually under the hood or inside the cabin.
In short, while there's no single definitive image, it's a small, black rectangular box with electrical terminals. Referencing your vehicle's documentation is crucial for accurate identification.
