Oil Pump Pick Up Tubes and Screens
A new Melling pick-up tube/oil screen assembly provides the lubrication oil as well as protection for your oil pump from materials that find their way into the engine oil supply system. Contaminates enter your oil system via engine wear, extended time between oil changes and other internal engine sources. These contaminates can interfere with the proper oil flow and pressure spring functions resulting in engine damage and/or failure. Melling suggests that a new properly installed oil pump pick-up tube/screen be a part of every oil pump installation. Several Melling oil pump applications are offered with an oil screen included.
