thanks Dark Knight , no noise I was just trying to find out as I make long trips , it seems like a much different set-up than the 5.0 no return , no pressure regulator on the fuel log, and even when you shut the kill switch in trunk it runs a few minutes...also there twice the price.... they even have a completely different way they mount in the tank...bolts in a large circle ...no twist off like the 5.0...seems stronger & better made all around ......
