Remember These Important Parts and Accessories

While shopping for your new Cummins oil pump, remember to pick up any additional products you need, such as these parts and accessories:

Oil pan gasket: As you replace your oil pump, you can also switch out your oil pan gasket to ensure that your engine has no leaks. These critical parts keep oil from entering sections of the engine where it can cause damage.
Oil filter: We recommend changing your oil filter every time that you change your oil. Since replacing your pump involves an oil change, you can also get an oil filter to ensure the best results.
Oil/fuel pressure switch: Some customers need to replace their engine's pressure switch as they change their oil pump so their boat can notify them when they have low oil pressure. Our pressure switches can connect in normally open or normally closed circuits.
Engine paint: Touch up worn enamel and give your new parts a seamless look with a coat of engine-safe spray paint.
Mechanical and electric gauges: Get an accurate reading on your oil levels by getting a new gauge in your oil pump order.
