I think there is an internal check valve in the new ones but the early units DMCH sold some of the check valves would not hold long enough.

You really should use an external valve with the new OEM style pumps and Kjet.
I removed the check valve after converting to EFI and you can hear the accumulator spring expand as the fuel drains back after key off.

It's the one I use and I believe it is the same one DMC uses.
