[QUOTE="MalcolmV8, post: 14446599, member: 8854"] I have not opened up the pumps so I have no idea if there really is a check valve or not. More correctly my answer should say they sure behave like they have one so there are no issues with staging the pumps. As I mentioned above even when I turn off the key they hold fuel pressure in the lines for some time. Whether there's a check valve in them or it's just that hard for fuel to reverse flow through them I have no idea. [/QUOTE]
