2. Apply a film of lubricating oil to the gasket of the new filter. Screw the filter on to the filter head until the gasket is
hand tight (an additional half to one turn after the filter makes contact with the gasket). Ensure the seal is intact when
replacing the spin-on filter.
3. Check for leaks when re-starting and pressurizing the system. The material trapped inside the filter can be inspected to
better understand the types of contaminants that have been removed from the tank.
The water block filters are used to remove entrained and emulsified water from the fuel. Saturation of the water block filter
will cause the pressure drop over the filter to increase.
When the pressure drop over the filter(s) blocks the flow of fuel, and the filter element is not changed, the bypass valve in the
filter will open and the system will idle. Unfiltered fuel will be pushed out of the system and return to the tank. If the situation
continues, the pump bypass may activate causing the system to idle.
