As of 2015, the average cost of an oil pump installation is between $300 to $1,000 depending on the car, labor cost and quality of pump used. The oil pump is a vital device that keeps the car running; if not replaced, it may cause damage to the car engine.
The cost of the oil pump itself can range from about $100 to $300. Accompanying parts such as the pump gasket, oil filters and pan gasket may also need replacement, which would increase the final cost. Because the work can be extensive, the labor cost for replacing an oil pump ranges from about $200 to $400.
