Failing Duramax Fuel Filter Housing Symptoms:
On Duramax trucks, the injector pump sucks fuel from the tank, creating a vacuum from the fuel tank through the fuel lines and filter. The fuel is pressurized once it reaches the injection pump, to the high pressures needed for the fuel injectors. A failing fuel filter housing will start to leak fuel and allow air to enter. This is usually accompanied with the following symptoms:
Fuel Leaks At The Fuel Filter Head
Engine Starts But Immediately Dies
Hard Start Conditions If The Truck Has Been Sitting For A Few Days
Engine Will Not Start Unless Manually Primed When Parked On Incline
Kit Includes:
Water In Fuel Plug

Nice, spacious leather wallet
Color: Dark Coffee Brown
Nice quality leather wallet, lots of places to put IDs and credit cards. I'll take it that it is RFID blocking, no way of testing that!! If you like to keep photos and other IDs in the clear plastic windows, you'll need to buy those separately. Still, this is a nice wallet, good quality, holds my "stuff" -- I'm happy!
