Understanding Fuel Filter Housings
A fuel filter housing comprises three critical components:Get more news about Fuel Filter Housing,you can vist our website!
Fuel Filter Head: This component includes the primer and fuel heater.
Water in Fuel Sensor: It screws into the bottom of the filter.
Filter (Filter Housing): Also known as the filter housing, this part plays a crucial role in maintaining clean fuel.
Importance of Fuel Filter Housings
Contaminant Removal: Fuel filter housings keep the fuel clean by filtering out impurities. This is especially vital for diesel engines, as contaminants can quickly wear down fuel injectors.
Tight Tolerances: Diesel engines have precise fuel injection systems. Any unfiltered particles act as abrasives, damaging injectors and leading to expensive replacements.
Composite Materials: While some fuel filters have all-metal construction, many Duramax engines use composite materials for their filters.
Common Failures
Seal Failure: O-ring seals at the top and bottom of the filter can leak. Air entering the system due to a leaking seal makes the engine hard to start and causes rough running.
Cracks in Filter Housing: Cracks in the housing lead to fuel leaks and immediate truck disablement.
Replacing Components
You can replace the three components individually or opt for a complete unit replacement. If any part within the fuel filter housing fails, your engine’s performance will suffer.
