Introduction
This Tool Operating Manual contains two filter installation procedures. This first procedure is for installing a primary filter system. This is a coarse filter and will protect the transfer pump from contamination in the oil. The second procedure outlines installing a secondary filter which is designed to protect injection pumps from contaminated oil. Fuel injection pumps used on the 3208 Engine are one example of a fuel injection pump that requires the secondary filter installation.It will be the dealer choice as to which optional filter is installed on the test stand. Determine what type of filtering will be required most often, and install the appropriate type of filtering system. These filters can only be added to the 15 horsepower test stands.Secondary Filter
