search for snap to connect (STC) fitting. It was a common issue and causes the truck to not start when hot. Let it sit for 30 min and it starts right up. It's a line on the HPOP that cracks over time and causes a slight leak.

 

I just want to make sure i am checking the right screw on my FICM. Looking at it from the drivers side fender. there is 3 screws on the left and 4 on the right. i am checking the top one on the right side. this is the correct one isnt it? thanks
