* Specialty Performance Parts Retailers: Companies like Summit Racing, Jegs, AmericanMuscle, and others specializing in Mustang parts will have a wide selection of high-volume fuel pumps and kits. These often include the pump itself, wiring harnesses (if necessary), and installation instructions. They'll offer pumps from various manufacturers with different flow rates and pressure capabilities.
* Online Marketplaces: Sites like eBay can be a source, but be cautious. Verify the seller's reputation and ensure the pump is new or in excellent condition. Used pumps might not be reliable.
* Local Performance Shops: Check with local auto parts stores or performance shops in your area. They may carry some high-volume pumps in stock, or be able to order them for you. This is helpful for immediate needs, but their selection might be more limited than online retailers.
* Manufacturer Websites: Some fuel pump manufacturers (e.g., Aeromotive, Holley, etc.) sell directly to consumers through their websites. This can be a good option if you know the specific brand you want.
Important Considerations:
* Flow Rate: High-volume pumps are rated by their flow rate (gallons per hour or liters per hour). You'll need to determine the appropriate flow rate based on your engine modifications. A pump that's too high-volume might not be necessary and could even be detrimental.
* Fuel Pressure: The pump's pressure rating should also be considered, as it needs to match or exceed the requirements of your fuel system.
* Installation: Installing a high-volume fuel pump can be challenging, requiring some mechanical skills. Some kits include instructions, but you might need professional installation if you're not comfortable working on your car's fuel system.
Before purchasing, it's always best to research the specific pump's specifications and compatibility with your 1998 Mustang GT and any modifications you've made. Using the wrong pump can damage your engine.
