The first image is of the new regulator and to show you how the return line is, and so I can ask what the silver thing is just under the regulator? The second image is to show how the return was blocked off and the car would run til flooding like this. I took the round silver thing out of the line and can see straight through it. Is it suppose to be that way like maybe a surge protector or it there suppose to be some kind of filter or valve in it?
