Duramax Fuel Filter Housing Delete
A Duramax fuel filter housing delete is a modification that removes the stock fuel filter housing from a GM Duramax diesel engine. This is typically done in conjunction with the installation of an aftermarket lift pump.
There are a few reasons why someone might choose to perform a fuel filter housing delete:
- Increased fuel flow: The stock fuel filter housing can be a restriction to fuel flow, especially when an aftermarket lift pump is installed. Deleting the housing allows for unrestricted fuel flow to the engine.
- Easier filter changes: Some aftermarket lift pumps come with their own built-in fuel filters. Deleting the housing can make it easier to change these filters, as they are typically located in a more accessible location than the stock filter.
- Weight savings: The stock fuel filter housing is made of metal and can be relatively heavy. Deleting the housing can save a small amount of weight.
Duramax Fuel Filter Housing Replacement process
Here’s a general overview of the process:
1. Locate the fuel filter housing
The fuel filter housing is typically located on the driver’s side of the engine, near the firewall.
2. Disconnect the battery
This is an important safety step to prevent electrical sparks when working on the fuel system.
3. Drain the fuel pressure
There are various methods to do this depending on your specific Duramax model.
4. Disconnect the electrical connector and fuel lines
Use the appropriate tools to disconnect the electrical connector and fuel lines from the housing.
5. Remove the mounting bolts
There will typically be two bolts holding the housing in place. Use the socket wrench to remove them.
6. Install the new housing
Carefully position the new housing and reverse the steps above to install it.
7. Prime the fuel system
This process involves manually pumping fuel through the system to remove air bubbles.
8. Reconnect the battery and start the engine
Check for any leaks and listen for any unusual engine noises. If everything seems normal, your Duramax fuel filter housing replacement is complete.
Duramax Fuel Filter Housing Problems
The Duramax fuel filter housing, specifically in models from 2001 to 2010, can encounter a few common problems:
- Air leaks
This is the most frequent issue, caused by worn-out O-rings within the housing assembly. Leaks allow air to enter the fuel system, affecting the ability to maintain prime and leading to:
- External fuel leaks
Though less common than air leaks, these can occur due to cracks in the housing itself or loose connections.
- Clogged filter
A clogged filter can restrict fuel flow and cause similar symptoms to air leaks, like extended cranking and decreased performance.
Diesel Fuel Filter Housing With Priming Pump
A diesel fuel filter housing with a priming pump is a combination unit that serves two purposes in a diesel engine’s fuel system:
- Filtering: It houses a replaceable filter element that removes contaminants like dirt, water, and rust particles from the fuel.
- Priming: It integrates a manual hand pump that helps purge air from the fuel system after filter replacement or when the engine has run out of fuel.
Duramax Fuel Pressure Test Port
Duramax fuel pressure test ports are located on the fuel return line near the engine’s driver-side firewall. They typically have a 1/8″ NPT thread for connecting a fuel pressure gauge.
Duramax Air In Fuel Symptoms
Air in your Duramax’s fuel system can cause several symptoms, including:
- Extended cranking: Engine takes longer to start after sitting.
- Stalling: Engine starts but sputters and dies.
- Power loss: Engine hesitates and lacks power under acceleration.
- Rough idle: Engine runs unevenly at idle speed.
Duramax Fuel Rail Pressure Too High – Reasons
Several issues can cause excessively high fuel rail pressure in your Duramax:
- Faulty fuel rail pressure sensor: This sensor sends incorrect readings to the engine computer, leading to improper pressure regulation.
- Defective pressure regulator valve: The valve fails to regulate pressure, causing the pump to overpressurize the fuel rail.
- Clogged fuel filter: A restricted filter limits fuel flow, forcing the pump to work harder and build excessive pressure.
- Internal high-pressure pump issue: Malfunctions within the pump can cause it to generate abnormally high pressure.
Lb7 Duramax Fuel Filter Housing
