Hello everyone, just joined here and I wanted to introduce myself as well as ask something. I have two pictures and I was curious what these parts are. I have a high idle. I recently replaced the fuel pump and I had difficulty starting, I was getting s crank no start situation. I figured out that if I unplugged the pump, tried to start it dry a few times to clear the fuel lines, then plug the fuel pump back in, it would start. I am driving a little more each day then I was before and that seems to be making a different as well. However it still seems to be running rich and I'm wondering what could cause that. Thank you so much!

Fuel pressure regulator?
