Edelbrock Fuel Pressure Regulator Carbureted 180 GPH 5-10 PSI -10 In/Out -6 Return Black

I ordered this Edelbrock fuel pressure regulator and it is missing the pressure adjustment screw for the top of the regulator. I tried to use the adjustment screw out of an old Holley regulator that I had but the threads are different. No way to adjust the regulator without the adjustment screw. I called Jegs to get it straightened out and was on the phone for nearly an hour and a half in total, mostly on hold. A representative told me that I would have to send it back to get credit, so I asked what exactly I needed to to do to send it back. The representative put me on hold again and I finally hung up without an answer on what to do. Edelbrock screwed up by not including the pressure adjustment screw and Jegs customer service sucks. Edelbrock and Jegs won on this one. I ended up ordering an Aeromotive regulator from Summit and had to next day air it.
