I ordered and received a pump from Amazon. The box came and it was the right Edelbrock 1725 box, just someone put a different pump in the box. There were two immediate giveaways of a problem. The 1725 has 3/8th fittings, the pump from the box had 5/8th fittings. The pump from the box had no Edelbrock decal on it, and the castings of the pump were substandard. Who switched the pump with an unlabeled pump? Don't know. There is a number stamped on the main casting: 3904LPP20K19. "Made In USA". I'm going to receive another pump from Amazon, hopefully the 1725 I initially ordered. That said, anyone who's installed the 1725 not have their expectations met? Edelbrock states a pressure regulator isn't necessary, is that your experience? The quality of many after market parts is substandard including 302 fuel pumps. With tax $150 for the 1725. Time is money - I wish I'd known at the beginning of my search for a fuel pump the made in USA Edelbrock was a part that would fit.Hopefully it will provide me with years of service. I once again have spent hours trying to work through finding the right part, hope the pump coming in the mail won't disappoint. John B Thanks gr8scott and all you guys for your help in getting through this!
