Either I damaged the o ring or I just needed to make sure it wasn't cockeyed as I know that causes leaks

I went to check the # of the fuel pump but could not pass the first step of the process : remove both the hoses from the filler neck...
Are those regular hoses? What diameter should I use I can't ifnd some on Rockauto.

The straps went off easily but i put them back until the hoses are off.

Added a larger Hayden trans cooler. Oem was half the size as y'all know. Only had to modify the top right corner for the grille to bolt back in. Question? Is the top connection at the radiator supposed to leak a few drops on startup after such an install? Leaked quite a bit until I had it warmed up, jiggled it around a bit and finally got it to one drop but that's at start up. Didn't drip on shroud or below after a 30 minute test drive. Was spotless before the install.

There should be no drops. You might want to fix that before it leaks a lot when you're least expecting it.

I removed my fuel pressure regulator and installed a service kit I just received. Seems that when I moved it from the old intake manifold to the Whipple fuel rail I left a tiny o-ring behind. Hopefully this fixes my fuel pressure leak-down issue that's causing a delayed startup.

When you installed the line, did you install the clip first and then push the line into the fitting until it clicked into place?
