Midwest's flagship center in Bolingbrook primarily deals with buying and selling fuel injectors and pumps while directing a fleet of pick-up and delivery vehicles around Greater Chicago. It also cleans and re-builds fuel injectors upon request as well as offering an exchange program, shipping UPS daily. Electronic injectors are also at Midwest's disposal, and its parts department maintains a large inventory to help minimize customer waiting time. Midwest's Bosch Diesel Service Center offers truck repair until 5 pm weekdays. You can also buy Midwest brand shirts on their website.
