Please check notes in each part listing to ensure the Pre-Heater Hose is correct for your 1966 MERCURY MARAUDER with a 6.4L 390 engine. Special restrictions like "California only" or "with sport package" may indicate a Pre-Heater Hose fits only certain 1966 MERCURY MARAUDER models.
Clicking a "More Info" link will display a picture and/or other details about that Pre-Heater Hose in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Pre-Heater Hose, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Fuel/Air parts, other MERCURY MARAUDER parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1966 MERCURY will not be lost if you switch.
