Deposits in the fuel system reduce fuel economy, impair drivability, and interfere with the proper operation of an engine. Deposits are a by-product of the combustion process and need to be removed on a regular basis. Cleaning the fuel injectors is only part of the solution! To restore performance and fuel economy along with eliminating hesitation, rough idle, and knocking we must clean the entire fuel delivery and air intake systems. VPS has developed a line of fuel products and delivery mechanisms that will accomplish these goals in many different ways.
