What walbro use ? When i put my walbro i have problem with the stock fuel line evry time the fuel pump hose going out.And the car it's runing but with extremly low fuel pressure.
Check you fuel hose inside in your gas tank or you fuel pump it's work good.
What kinde of fuel pressure regulator are you use. Be sure it's right installed.

Check the o-ring on your fuel pump and make sure you didn't tear it.
