To find the correct filter, you need to:
1. Check your existing fuel filter: The filter itself will have a part number printed on it. This is the easiest and most accurate way to find a replacement.
2. Check your owner's manual: Your owner's manual should list the correct fuel filter part number.
3. Check a parts store online or in person: Provide them with your truck's year, make, and model. They can cross-reference your vehicle information to find the correct filter. Be prepared to tell them it's a 7.3L IDI, not a Power Stroke.
Popular filter brands for this engine often include Baldwin, Fleetguard, Wix, and Motorcraft (Ford's brand). However, using the part number from your old filter or your owner's manual is crucial to ensure a proper fit. Don't rely solely on the engine size.
