When removing fuel injectors from a high-mileage engine, do you consider the possibility of built-up debris such as rust and carbon being lodged in the injector seats? We certainly hope you do, because that residue can prevent a new injector from installing and sealing properly, and thus cause a leak.

An improper seal may also allow gases, fuel, and compression to pass around the injector, creating a loss of power. So, each part of the injector seat should be cleaned whenever an injector is removed or replaced. Removing dirt and debris from injector seats is exactly what 8090S Professional Diesel Injector-Seat Cleaning Kit does.

The kit features three types of brushes: Helix Brushes, Two-Stage Brushes and Bore Brushes. Each brush type is designed for cleaning specific areas of an injector seat.

A driver handle with a quick-lock coupler and two extensions is also included, as is an assortment of swabs. These brushes and swabs vary in size and can be used for multiple and different applications.
