This oil pump pickup allows you to use a High Volume oil pump in any mustang oil pan application. This is a copy of the factory SHELBY GT500 design and may look different than OEM type pickups but clears most windage tray and stud setups in 4.6 and 5.4 blocks with a Mustang pan. This tube is 15/16" in diameter for high volume pumps and is special. The standard 4.6 and 5.4 SOHC pickup tube is 13/16" and WILL NOT WORK with high volume and high pressure pumps. Fits the following high volume oil pumps in Mustang oil pans: Ford Racing High Volume, Ford Racing High Pressure, Melling Cobra pumps, Melling Hi Perf billet gear 10227, Melling 10340, Melling M227 Cobra, Melling M340, Melling M360
