In February, I ordered an Edelbrock fuel regulator (17401) from Summit. Car was in storage and regulator has been in/out of stock, so I grabbed it when I could. I didn't open the package until last week and the AN fitting on return side was missing. I called Summit customer service and they offered to either return and replace or have Edelbrock drop ship the part to me. I chose the later, and to the exact eta, the part arrived. Excellent Customer Service from Summit and Edelbrock
