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

Beautiful gift for matcha fans!
Color: Pink, Color: Pink
My daughter is obsessed with matcha, so when I found this for Easter I knew it was the one. She makes her own latte every single morning, so this fit perfectly into her routine. The packaging alone is gorgeous — the colors worked beautifully with the Easter basket without me having to do much styling at all. Everything she needs to make her matcha was included in the box, nothing missing, nothing to track down separately. I was so happy I stumbled across this, and she absolutely loved it. Honestly one of those gifts that just lands exactly right.
