If oil is the blood in your engine then your Mercury Montclair oil pump is the heart. When your oil pump becomes old and worn out it will not supply enough oil pressure to the crankshaft. This in turn will cause bearings to fail and eventually cause the motor to seize completely. To prevent this type of catastrophic damage it is important to replace your unit with a brand new replacement Mercury Montclair oil pump. Here at Andy's Auto Sport we offer a great selection of Mercury Montclair oil pumps for you to choose from. Whether you want a simple replacement pump or a high-performance unit, you are sure to find the perfect part for your needs in our expansive collection.

While a standard replacement pump is fine for a stock motor, if you are running power adding modifications it is a good idea to step up to a high-flow Mercury Montclair oil pump. Uprated oil pumps have increased capacity so that they can provide improved pressure and flow to ensure that your motor stays lubricated even under intense racing conditions. With a high-flow oil pump you can protect the investment under your hood and drive your vehicle with confidence knowing it is getting the lubrication it needs.
