Major Customer [Abstract]
Major Customers, Policy [Policy Text Block]	Major Customers One customer, Susser Petroleum Company ("Susser"), accounted for more than 10% of consolidated net sales for the year ended December 31, 2013. The amount of revenues from Susser during the year ended December 31, 2013 were $160.8 million, which represented 17.7% of our total consolidated net sales and 19.0% of our total net sales in our wholesale marketing and terminalling segment. Delek accounted for 84.2% of our total net sales in our pipelines and transportation segment during the year ended December 31, 2013. Two customers accounted for more than 10% of consolidated net sales for the years ended December 31, 2012 and 2011. During the year ended December 31, 2012, Delek accounted for 20.9% and Susser accounted for 17.5% of our total revenues, respectively, in our wholesale marketing and terminalling segment. Delek accounted for 88.7% our our revenues in our pipelines and transportation segment during the year ended December 31, 2012. The amount of revenues from Susser were $178.9 million and $154.6 million for the years ended December 31, 2012 and 2011 respectively, and are included in our wholesale marketing and terminalling segment. The amount of revenues from Delek were $236.7 million and $27.8 million for the years ended December 31, 2012 and 2011, respectively. We believe that gross margin is a better measure of performance of our business than revenue, particularly in our wholesale marketing and terminalling segment, as total revenue varies with the price of the underlying product, such as a gallon of finished product. Accordingly, we believe that, for the purpose of evaluating our business on a customer-specific basis, gross margin, which we define as net sales less cost of goods sold, is a more accurate indicator to reflect the importance of certain customers to our operations. Delek accounted for 72.2% and 84.0% of our gross margin in our wholesale marketing and terminalling segment and our pipelines and transportation segment, respectively, in the year ended December 31, 2013. Delek accounted for 51.2% and 57.3% of our Predecessor's gross margin in our wholesale and terminalling segment in the years ended December 31, 2012 and 2011, respectively, and for 88.7% and 46.0% of our gross margin in our pipelines and transportation segment, in the years ended December 31, 2012 and 2011, respectively.
