Line burst

The 3 inch rubber submersible line connecting the EP381 pump to the sending unit supply tube ruptured twice. 2015 5.3, 1987 fuel tank and sending unit, corvette filter/regulator. New 5/16 return line, new braided stainless 6 AN supply line. All lines are secure, unobstructed and connected to correct location on sending unit. New fuel pump, new ‘87 tank, filter regulator replaced about 5 months and 500 miles ago. The truck runs fine for a few days and blows this line for some reason. This is a friends ‘85 squarebody. Any thoughts? Bad filter/regulator?
