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 overall
Size: Large, Color: Red Flower
Great looking shirt even though collar is not especially stable. Seem like it will be durable. The one thing I have noticed about these moisture wicking shirts is they don’t seem to be especially breathable which leads too more moisture. Good fit, great color and cut just right for a guy who is no longer like Big John, “broad at the shoulders and narrow at the hips” with a tail just right for the untucked look.

Fantastic shirt for the big and tall man
Size: 4X-Large, Color: White Peak
We bought multiple shirts from Obla recently in different colors/prints. They are an incredible value for the price. The material is so nice, and they wash up well. The collar is more structured, and makes the shirt more polished looking. My 6'5" 300lb husband was very comfortable and looked great in the 4XL. Would highly recommend this brand, and will be customers for life!

Cool, Comfortable, and Perfect for the Course
Size: Large, Color: White Colored Dots
This golf polo is a great mix of comfort and performance. The dry-fit fabric keeps you cool and dry, even on warm days, and the material feels lightweight and breathable.
It has a clean, modern look that works well on the golf course or for casual wear. The fit is comfortable and moves easily with you. Overall, a solid, stylish polo at a great value.

Great shirt!
Size: X-Large, Color: Purple Buffalo
Love it! Light, stretchy, and breathable! The shirt itself is so nice to wear, I’ll probably buy other patterns!
I bought a dozen of these in different sizes for a golf tournament. Sizes ran true. Nice athletic fit!
This pattern made us just the right amount of obnoxious out on the course! Great vibrant violet color from afar, cool pattern up close!

Shoe
Size: 10-11 Women/9-10 Men, Color: 1a-stripe Black-2
These beach shoes have been super comfortable and practical. They fit well, are lightweight, and the sole has great grip, even on wet surfaces. I used them at the beach and by the pool, and they protected my feet really well from hot sand and rocks. They also dry quickly and are easy to carry.
