I have a regulator left over from my 97 Cobra and I'm trying to identify the manufacturer so I can sell it. It looks identical to a stock regulator except the vacuum nipple has a threaded screw to adjust the pressure. The P/N printed on the body is 185JJBA. Thanks for your help.
Tim, I don't think stock regulators have an adjustable fitting on the top to regulate fuel pressure. The one you linked has an open vacuum fitting, like most stock regulators.

They do need vacuum. I remember removing the hose, adjusting the fuel pressure and then replacing the hose back on top. It does not remain exposed. As far as modification, I can't say. I remember buying it that way from a friend.
