Why is my fuel filter leaking?
Why is my fuel filter leaking?
What causes a fuel filter to leak? The cause is usually something rubbing up against the gas line over an extended period, age degeneration or the line coming into contact with something sharp. It’s easier to create a leak than find the source.
Why is my fuel filter leaking on my Duramax truck?
External fuel leaks can develop as well, and will be evidenced by fuel puddles on the ground or on top of the filter assembly. If you have a high-mileage Duramax-powered truck and suspect that it’s losing its prime, or you have seen evidence of fuel leaks from the filter head, you’ll want to address the problem as soon as possible.
Why is my Duramax water pump leaking coolant?
The OEM water pump uses an iron impeller which makes it much more durable than the plastic impeller used on newer models. Instead, over time the seals can deteriorate resulting in lower coolant levels because of coolant loss. This can cause overheating issues. Leaks also reduce pressure, causing the coolant system to inadequately supply coolant.
Can a leaking O ring cause a Duramax to hard start?
If you’re going to own an LB7 Duramax over an extended period of time, the odds are you will experience this problem. A leaking o-ring not only results in a fuel leak, but air can also enter the fuel system. This causes various performance issues, hard starts, and even engine codes.
Can a leaking fuel filter cause a hard start?
A leaking o-ring not only results in a fuel leak, but air can also enter the fuel system. This causes various performance issues, hard starts, and even engine codes. There are inexpensive kits to totally replace the o-rings found on the fuel filter housing unit.

What kind of problems does a Duramax engine have?
The 5 Most Common LB7 Duramax Engine Problems 1 Fuel Injector Failure 2 Water Pump Failure 3 Fuel Filter Housing O-ring Leaks 4 Blown Head Gasket 5 Overheating (fan clutch problems, radiator gunk)
Where does coolant leak on a Duramax diesel engine?
Coolant also may leak from the coolant hoses at the Emission Reduction Fluid Injector (DEF injector). (Fig. 10) The radiator surge tank uses two different radiator surge tank caps. The radiator surge tank cap that vents pressure in the event of excessive cooling system pressure is located on the lower outboard side of the radiator surge tank.
