FASS Drop-In Series Duramax FAQ
- Will the Drop-In Series System for the L5P Create Excessive Back Pressure on the Lift Pump?
In short, no! Through extensive engineering and testing, the FASS R&D team was able to decrease pressure drop (differential pressure) approximately 1 PSI from the OEM filtration system. This was accomplished by maximizing the internal porting size to allow a system that flows more freely in addition to adding superior filtration.
- Why Does the Drop-In Series for the L5P Utilize an OEM Water Separator?
The reason we utilize the OEM water separator is due to the design of the OEM water in fuel sensor/fuel heater. We are the only Drop-In style system that allows the water in fuel sensor to properly function as they must be on the DIRTY SIDE of the water separator element to detect the water before it makes it to the clean side. If the sensor is placed on the clean side of the element, by the time the sensor detects the water it is too late! With the Drop-In Series FASS, you will get properly functioning water in fuel light and fuel heater!
