Alan, looks like it's a deadhead type regulator. According to the instructions (see the link below), it's recommended for the Mallory 140 fuel pump and both of us have a lot of experience with those pumps! http://www.jegs.com/InstallationInstructions/600/650/650-4207.pdf
Paul, I will take it. I just bought one from Summit (showed up yesterday!) for twice that amount. I have to return some other stuff too, so I will return the regulator. Let me know how you want payment.
